We tried SUSE Enterprise Linux for our new mail server, but we ran in to the exact problem you are having. We are now trying to get our money back for SLES as our FreeBSD mail server purrs along without a hitch. The ports collection is the greatest thing since sliced peanut butter. Zero dependency problems, because everything is built from source. I know it doesn't help your case, but for future builds it is something you might want to consider.
[IMGate] Re: IMGate/Postfix under Ubuntu/Debian
Aaron, First of all, you might want to uninstall any programs that you aren't actually using. That will not only save you some disk space, but keep dependency issues to a minimum. Secondly, you might also try editing the /etc/apt/sources.list directly = and follow the directions in the # comments section in order to upgrade to = the unsupported software in Ubuntu. I was able to upgrade to the latest version of Postfix by following the directions in that file. It is very simple. Just comment/uncomment a couple of lines in the text file. Next, you might try just running apt-get from the command line, rather = than Synaptic. Sometimes apt-get seems better at solving dependency problems. After you have modified the above file, just go to the command line and enter apt-get upgrade postfix (no quotes). That will hopefully do the trick. If that doesn't work, you might consider just ditching Ubuntu altogether = and install the Testing version of Debian. I ended-up doing that for what is = now my main IMGate box, and it was a lot less of a hassle than I thought it would be. The install CD-ROM is only like 100MB, and although it is = called Testing, I have found that version to be rock solid, at least for all = of the apps that I am running. The main stuff that I have on the box is = Postfix (duh!), BIND 9, Webmin, PERL, SSH, etc. It is very lean and mean, and my average CPU usage is something like .01%. It has blocked over 3,200 = messages so far today, running a 2.6 GHz Athlon XP, a single 20GB IDE drive, 1GB = of PC133 RAM and Len's scripts, along with my own set of limited rules and domain blacklist, which alone is blocking more traffic than all of the = RBLs combined.

What does the advanced config cost? $600 for one MX, $1100 for 2 MX, with the backup mirroring the first, and 30 days personal support. fresh install of advanced IMGate, or upgrade of basic IMGAte, same price. this info is in the basic IMGate readme.txt. Len
[IMGate] Re: IMGate/Postfix under Ubuntu/Debian
From: William Van Hefner [EMAIL PROTECTED] What have you thought of IMGATE so far? How effective is it=20 compared to your previous solution? So far, I am only using IMGate as an anti-spam gateway for my secondary (Imail) mail server. I am slowly working on replacing that box = altogether, and will eventually put an IMGate/Postfix box in front of my main mail server as well, as soon as I am comfortable enough with knowing how to = run snip I'll probably also integrate my SortMonster/MessageSniffer filter into spamassassin eventually as well. That is by far my most effective filter = on the IMail machine. Long-term, I will eventually scrap IMail altogether, = and just run a pure Postfix box behind the IMgate box. I have a LONG way to = go before I will feel comfortable enough to do that though. Postfix behind IMGate? IMGate is Postfix. This is not Windo$, you don't need the redundancy. Now, many will run Spamassassin/virus filtering on a second box, and that would not need Postfix. Now, for replacing IMail, then the second box could be Courier/Cyrous per Keith's example, and Postfix would not be needed on that box either. I've been happily running IMGate(Postfix) in front of my IMail/Exchange boxes for several years now! :-) I'm getting ready to start setting up a replacement for IMail, probably based on Courier.
[IMGate] Re: IMGate/Postfix under Ubuntu/Debian
When it comes to imail and protecting against dictionary attacks, you have only imail and blackice that I know of. Imail add-ons (declkude or our own , mxGuard) can not protect against them because Imail takes care of all the smtp communications - then hands the message off to the add-on. Postfix is always a good choice, no matter what you are trying to do. - Original Message - From: Steve Cobb [EMAIL PROTECTED] To: IMGate@mgw2.MEIway.com Sent: Tuesday, August 30, 2005 7:31 AM Subject: [IMGate] Re: IMGate/Postfix under Ubuntu/Debian You might look at mxguard. They have a SPAM and Virus solution for Imail that is very reasonable. Not very customizable however. Are you running Blackice on your Imail server?

I'm looking for a spam solution. I'm running ASSP but it makes a lot of mistakes. Declude is insanely expensive and I'm not willing to spend that kind of money on their solution.

How effective is it compared to your previous solution? My previous solution was no solution at all :-) IMail 7 has no way of preventing massive distributed dictionary attacks, and our IMail box was being brought down with frightening regularity (this is a 3ghz server, mind you). A little 233mhz Pentium-MMX running Linux and IMGate sitting as a proxy between the outside world and IMail was enough to stave it off. I've since added a second IMGate box largely as a failover, but also to take some load off. I'm very impressed with IMGate/Postfix, and in the long run, we'll probably abandon Windows-based email solutions entirely, and use one of the boxes as the mail server. -- Aaron Clausen
