What kind of mail server do you use?
There are a great deal of mail web servers around. Microsoft Exchange has actually been the leading company mail web server in the venture on Windows, yet I've been making use of Kerio Mailserver for a long period of time currently and also am still asking yourself if there aren't any far better remedies.
Which mail-server do you make use of, and also why?
What attribute make a details mail-server 'attract attention'?
Both * NIX and also Windows applications rate.
I can not claim sufficient excellent concerning SmarterMail: http://www.smartertools.com/SmarterMail/Features/Windows-Mail-Server-Software-Webmail-Exchange-Alternative.aspx
My experience with the application has actually been strong. We make use of for it customer mail organizing. We organize around 200+customers, 1000+customers, and also plus a variety of SMTP portals. It is rather adaptable too.
And also for local business with under 10 customers, it is free: http://www.smartertools.com/SmarterMail/Compare-Mail-Server-Editions.aspx
I made use of Qmail for several years - primarily due to the fact that I invested a great deal of time keeping a tool - sized Qmail installment for among my companies a couple of years earlier.
I lately relocated all my email from Qmail to Exim, and also took care of to (primarily) manuscript the movement of all the digital domain names. I additionally relocated from making use of Courier to Dovecot for IMAP and also POP3.
http://struction.de/projects/HOWTO_VirtualMail_Exim-MySQL-Spamassassin-ClamAV-Dovecot/index?set_style=clean is an excellent overview on incorporating Exim with ClamAV, Spamassassin, Dovecot with a MySQL backend.
if you read concerning sendmail in all you promptly uncover its background of "bug of the week". Various other remedies have actually appeared ever since, actually a whole lot.
Postfix makes an excellent decrease in replacment.
Qmail proclaims its accuracy and also security.
I recognize extra concerning SELinux than qmail so I take my opportunities with having the proper SELinux plan (ie personalized SELinux plan, though the default needs to be great, effectively set up certainly) with a decrease in sendmail substitute.
I such as Unison as it incorporates all my interactions devices in one application - really straightforward as you accessibility email/im and also telephone regulations from one straightforward user interface
Postfix+postfixadmin+dovecot and also rouncube webmail (w/postfixadmin plugin), all making use of a MySQL backend.
Merely due to the fact that it is free and also rock secure.
Possibly mosting likely to relocate to Exchange when I have the allocate it. I intend to integrate my schedule from my smart device (our sales group - actually - desires it).
Groupwise. Web server - side has actually been ROCK SOLID given that the button to OES, which is primarily SLES. The customer is natively 'go across - system' (* nix/Mac one is Java), so if you remain in a Mac/Windows/Linux setting, you do not need to compel individuals to have a Windows desktop computer or have problem with the dreadful expectation internet accessibility customer when not making use of Internet Explorer.
Groupwise Web Access, Mobile customers, and so on do not take a PHD and also 3 years of training on a high hill in Washington State to release ... unlike OWA using HTTPS.
On the whole, it is still a little a weird duck, yet it is actually wonderful to have a venture mail system that you can install and also run without a frustration.
Exchange, largely to make sure that we can have a solitary supplier client/server system to make sure that if we get any kind of "funnies" we will not have each supplier attempting at fault the various other (a really vital factor IMO). Solitary join is additionally a critical variable.
We additionally have Domino readily available yet - in addition to one evangelist - the concensus is that the customer is not something we would love to provide to our customers.
I made use of Sendmail for years. Nonetheless, when I required to conquer my ISP is mail dimension restriction, i.e. the dimension of a specific email, I began making use of a business relay solution. The business relay solution calls for verification each time you send email. At the time, and also it might still hold true I do not recognize, Sendmail did not sustain this. Subsequently, I required a safe and secure MTA that did sustain this device which become Postfix. I've currently made use of Postfix for numerous years and also it is functioned wonderful. It was very easy to arrangement, at the very least contrasted to Sendmail, and also it does not require the very same variety of updates to maintain it safeguard as Sendmail did, i.e. it is rather secure and also safe and secure.
I changed our email to Google Apps for Domains back in mid '07 and also never ever recalled. It is been superb for obstructing spam. I also rather have to have every person utilizing it via the internet and also not a desktop computer customer, I just have one hold up that demands making use of Outlook. I've located it actually valuable for on-line cooperation devices & sharing records & schedule occasions.
Exim throughout. Why?
- Gladly withdraws to our RDMS of selection.
- Arrangement documents facilitate analysis.
- Log documents are conveniently read and also analyzed.
- Documents is succinct.
- Ranges well.
- Straightforward to screw in non - typical distribution alternatives without being hackish.
I've needed to make use of sendmail and also qmail greatly in the past. And also still today, periodically. Both of which confirm just to create me tremendous discomfort whenever our courses go across.
We are largely a Windows store, yet like the OP, we make use of Kerio Mailserver as opposed to Exchange for our inner groupware demands.
Our internet sites send a lots of email. All this email and also also email from our company Kerio server are sent out using a mailhub running Postfix.
I make use of Courier. It can absolutely take care of load and also it is not a PITA to set up.
I made use of qmail for some time years back. It was an intriguing understanding workout, specifically including "added" points so I can do points like neighborhood passing on. Nonetheless, I restored my web server some while after that and also considering all the initiative called for to get qmail going once more, I asked "why am I troubling?" Already, I had actually located Courier - IMAP to give IMAP accessibility to my maildir storage space and also during the remainder of the Courier MTA had actually been launched. It was a lot easier to install and also a lot a lot easier to set up than qmail, so my choice was made.
I have not attempted Exim, yet I needed to collaborate with Postfix at one work and also was really upset at its intricate arrangement. I needed to make it approve email for non - current customers and also pass it to a manuscript for our application (which took care of email intermally). Postfix made this needlessly hard IMO, yet the sysadmin would not sanction an adjustment to an additional MTA.
The only crease with Courier is that the reducing side MTA devices (as an example SPF assistance, grey - listing) are a little bit behind every little thing else as a result of its tiny share. And also it does not hop on 100% with fetchmail sending out to it, for one reason or another I could not identify.
Exchange is a respectable groupware customer, and also benefit No. 1 [ * ] is Activesync (email+schedule sync) which releases us from relying upon Blackberry:)
Having claimed that, I would not make an exchange web server straight net encountering as the mass of mail obtained by a regular company MTA is void (spam etc) and also the price per message of running a reliable exchange web server is a lot greater that a strong *nix based MTA.
Exim is (IMHO, and also as stated) one of the most adaptable, secure and also source reliable means of taking care of huge or tiny quantities of email - you can have spam/virus filtering system with a couple of added applications and also any kind of regulations based adaptability called for making use of the exim filter system. I have actually never ever found a mail need that could not be taken care of by exim (and also I've had some weird needs) and also the documents and also newsletter assistance is wonderful.
My common arrangement is Internet - > Exim - > inner Exchange web server with a little NAT for energetic sync and also expectation internet accessibility. Scalable, safe and secure & very easy to take care of.
[ * ] for me. I assume other individuals like it for various other factors ...:)
I've made use of sendmail, qmail, and also exim. Of those I favor exim, though qmail is alright though I bear in mind management to be irritating. I attempt to stay clear of sendmail as high as feasible.
If I were aiming to set up a new mail web server today I would certainly aim to exim, exchange, and also gmail for your domain name, relying on the certain usage instance. I made use of to organize my very own individual mail today I simply make use of gmail (the spam filtering system and also prevalent schedule is a big win).
I'm presently making use of hMailServer to host email for 5 various domain names.
I'm making use of SquirrelMail to give webmail to those domain names.
This is working on a Windows 2003 R2 box with IIS6 to offer the webmail. The major factors I'm running this mix is due to the fact that both programs are free, and also do not require calendaring right now. These are additionally reasonably pain-free for someone that has actually just done Windows.
Our mailsystem is based around MS Exchange , as there does not appear to be much competitors to it for the cooperation devices (ie. shared calendaring, etc)
But past that we make use of postfix with virtualmin to permit divisions to handle their very own domain name pen names and also pop3 mail boxes.
And also all of this rests behind 2 postfix / amavisd - new / spamassasin / clamav based mail filters. There is a wonderful tutorial on establishing this all up at http://www200.pair.com/mecham/spam/
I'm a qmail customer. I assume qmail would certainly be an uncertain selection now, considered that djb, it's writer, hasn't upgraded the core software program in years and also appears withdrawn in either doing so or launching the software program under a certificate that would certainly permit it to be forked in valuable means. (qmail's certificate permits spots, yet not straight redistribution of changed variations. This is rather bothersome).
Nonetheless, I would certainly be remiss if I really did not state the EXCELLENT software program I've made use of to gather incorporated qmail web servers for the previous numerous years : Matt Simerson's mail toaster oven. http://mail-toaster.org/
Exchange 2007, it's a hog to run and also supervise, despite having Powershell, yet the customer - experience is customarily tough to match (specifically with very easy - to - take care of Server Activesync assistance for all sort of smart phones).
The 2007 variation is extra modular and also sustains thinner portal duties which can lower several of the source hoginess I presume, minimizing some or all demands for alternative front - end mail web servers ...
Facing the net via Microsoft ISA 2006 for the minute - I kinda love that point for some factor. It's like, a durable firewall with excellent application layer filtering system, very easy SSL linking, with a straightforward to make use of user interface, that sustains very easy clustering. And also it's from Microsoft ... it's kinda unsubstantiated in fact, I need to jab at it consistently simply to see that it's actual. There's a more recent variation around, relabelled right into the Forefront namespace nowadays I assume, Threat Management Gateway or something aggravating like that.
First 3 years, Sendmail+Amavis (shell - manuscript variation). I did a little mod to the manuscript to catch add-ons by expansion.
Last 7 years, Postfix+Amavis, and also in the last 3 - 4 years, Dovecot. Limited, well - incorporated. Catches far better than 90% spam on first pass, captures 100% of malware on first pass. Dovecot gives rapid accessibility to mail boxes using IMAP - biggest box is reduced - 5 - figures and also lots in much less than 5 secs.
We're including a solitary in - residence Exchange web server this year, possibly finishing the change in 2 - 3 months. The Postfix arrangement will certainly remain to function as a scanning portal, and also give IMAP accessibility to Exchange (using Dovecot's proxy attributes) from the exterior.
I have actually been making use of ModusMail by Vircom (for Windows) for a variety of years with wonderful success. There are 2 key factors that I utilize it. One is that it is an exceptionally attribute - abundant, fully grown item. It can incorporate with nearly anything else that I require, sustains safe and secure links, and also has a really, great anti - spam remedy that is frequently being upgraded by a committed group of specialists, etc The 2nd factor is that it calls for really little upkeep. The software program virtually runs itself. We offer consumers accessibility to handle their very own mail boxes, we create records for audit so they can bill as necessary, and also seldom need to hang around "handling" the remedy. For bigger ventures or scenarios where e - mail definitely can not drop, Vircom additionally supplies a collection remedies where 2 of them can operate in tandem to make certain maximum uptime.
Currently for the disadvantages. No system is excellent, so there are bound to be some points that individuals will not such as concerning any kind of remedy. For ModusMail, the first is price. It is pricey, yes, yet worth every dime in the quantity of management time we conserve by utilizing it. The 2nd is that is it exclusive software program. For me this isn't much of a trouble, yet some individuals would certainly howl bloody murder if they can not see the resource code, to make sure that is a possible concern. The various other disadvantage is that is is a pure e - mail web server, not a cooperation system like Exchange. ModusMail takes care of e - mail using SMTP, POP, and also IMAP. It ships with a webmail application that includes standard calls, yet that's concerning it. If you're seeking team calendaring or various other cooperation features, ModusMail is except you.
Since this writing, ModusMail goes to variation 4.6, so several of the above might not use if you're reviewing this after a new variation is launched.
We make use of Zimbra. It's more affordable than Exchange, makes use of open resource modern technologies, the Desktop customer works with Windows, Linux and also Non-PPC Mac's.
The web server section is additionally a really simple install on a Debian box, yet works on Windows too.
Postfix ... and also for the why http://www.redhat.com/support/resources/howto/RH-postfix-HOWTO/c49.html
My firm makes use of Exchange for cooperation, yet I made them make use of Exim for the portals. Exim is one of the most adaptable mail web server I've ever before seen and also is a pleasure to make use of and also I could not visualize attempting to do several of things I'm asked to do with just Exchange (domain name filtering system based upon regexp, stabilizing domain names to make sure that our users in exchange just have one domain name and also our 20 public domain names still function, taking care of the reality that presently an offered lp @domain name can exist in 3 various systems (legacy-linux, Lotus, and also Exchange ), etc )
