The list has gone quiet for a little while so I thought I'd pipe up. I wanted to let you all know how my testing has gone so far. I am still running 8.22 on our production server, but am testing 2006.02 on my demo server.
(On a side note, I don't know why everyone doesn't test a new version of a product thoroughly, themselves, before upgrading their production servers. I am grateful for learning from the early-adopters what to look out for, but I feel bad for the administrators that write in franticly looking for help for a broken server after they do an upgrade. I'm not one to be giving other much more proficient administrators advice, but I hope they learn a little from the experience and build a test server next time. It is worth its weight in gold when it comes to avoiding down time from software upgrades.) I have a 1ghz P3 Dell Optiplex desktop that is my test mule. Woefully low on cpu and memory compared to a server, it works fine with only a few users accessing the apps. I have been sending about 1000 emails a day to it and haven't had any issues with the qmgr, pop, or smtp. We had an issue with Ldap not having a top level combined container for lookup as our SMTP gateway's (ASSP) ldap lookup isn't configurable, as written, to look at more than one container so we had to get creative :o). As far as Imap and Imail's new webmail access, well frankly I was worried when I found out they discontinued their original webmail service. My earlier testing with Imail's imap and SquirrelMail were not very positive in comparison to other email server programs and their imap. After installing I was not surprised to find that the Webmail, though very pretty, was so slow as to be almost unusable with more than a handful of emails in the Main.mbx folder. A folder with 200-300 emails would timeout trying to display the first 25. This occurred using Imail's webmail as well as Squirrelmail webmail running on Apache. When switching over to a different IMAP server, stopping Imail's Imap, both Imail's and SquirrelMail's webmail would display the contents of large folders with >500 emails with no trouble. This was disturbing so I set up a port redirector on the demo server and pointed demo:143 to production:143 and fired up IMAP on 8.22 running on our production server, an older Dell PE2450 733mhz x 2 with 2GB ram that handles our 5000 emails a day checked for AV and anti-spam, with no trouble and idles most of the time. Now when I ran Imail2006 Webmail on demo it connected to the IMAP service on my production server. It was far faster but still quite a bit slower than accessing the same folders using 8.22's webmail and was useless accessing one of my spam archives, 25MB with over 12k emails in it that 8.22's webmail could open fine. Then mysteriously, it changed! For the better! :o) Later that evening after some maintenance and a reboot, it was completely different. It was night and day, much faster than before. Almost completely functional, fairly fast access to mailboxes containing over 1000 emails (but still not able to open my mbx with 12250 emails). I don't know what change caused the improvement, but I did uninstall some leftover test software and added a missing DLL to my real-time AV scanner. I'm going to try to pinpoint the culprit and my thoughts point at the AV software. We'll see. Feature request: why oh why can't we have a more secure way to display the email in webmail? There is no option besides html and full display of linked spammer photos. SquirrelMail has an option to display email as plain text by default, and OE6 on XP SP2 has a great feature that blocks external images and gives the user the ability to click a button (bar) to see them. These would be excellent security minded additions to the current webmail. Thanks for reading this far and thanks Ipswitsh, for a great product over the years.
