RE: [IMail Forum] IMAP IS SLOW AFTER UPGRADE

Hello Tom,

 

As we have seen in the past, it sounds like the upgrade found an underlying hardware/software problem that was not evident before.  Going back to 7.1 will most likely not fix your problem.

 

For comparison, I have 8.01, I have IMAPers and POPers.  The CEO's IMAP account is 1.3GB (yeah it sucks), when he checks his e-mail from home (he has a cable modem we have T1), it takes 5 seconds max to sync his main folder.  We have been able to speed his up even more if we tell Outlook not to sync *every* foler each time it checks for new mail.  This may or may not be doable for you depending upon how there folders are setup and what kind of processing rules you have.

 

I have also been able to speed up the access time by breaking his archives into small mailboxes (it seems Diskeeper can handle them easier).  I usually break them apart by date.

 

 

I'm not sure if any of this helps, but don't put all of your hopes on going back to 7.1x.  Let's reasearch the problem a bit more before we give up.

 

 

Travis

FYI

I called support and they told me to upgrade to 8.01 which I have done.  The IMAP headers are still fetching really slow.  I am considering rebuilding to v7.1.  My users would rather deal with the spam than the slow response of fetching mail.

Was this affecting your users fetching mail from your server?  It seems to me that the SPAM filtering would slow down the mail delivery to the box, but not the client.  Our mail delivery to our mail server seems to be fine, but when our user attempt to check their mail boxes with IMAP the fetching of the headers are painfully slow.  How can this be improved?

 Hi,We found that some of the Blacklist servers were not responding (check your spam log) so were slowing mail delivery. We turned off all of them apart from Spanhaus and Spamcop and all is well.Just a thought!  Mark Walker

I upgraded my Imail Server to 8.0 about a month agao and the upgrade went smoothly.  Everyting seemed to be working fine.  Recenlty, however,  I have been getting a lot of complaints from my users that email is now slower.  We use Outlook 2002 with an IMAP connection to the Imail server and whenever the folders synch up with the server it takes a lot longer than before the upgrade.  We are a small organization with less then 100 users and the server has plenty of resources (512MB RAM, 1.2Ghz Intel PentiumIII, Windows 2000 SP3,Imail directory on a 25GB partition). I do have the anit-spam blacklist servers and statistical filtering in use (which is new of course), but this should not affect my users connections with IMAP to fetch their messages. I do not even know where to begin.Any help would be appreciated.ThanksTom
