You will want to edit the general.cfg file kept in /var/opt/scalix/??/s/sys for Scalix 11 or /var/opt/scalix/sys/general.cfg for Scalix 10.

There is a line called IMAP_CONNECTION_LIMIT. Set that to something higher than what you have.

Then restart the IMAP server with omoff -d0 -w imap then omon imap

It's already set to 500.. the config file states "note that many IMAP clients have several
# connections for each IMAP session.", however, we have less then 50 users on the system, i'll set to 2K and report back

Run: 'ps -ef |grep imap |wc -l'

If that returns a number much less than 500, then the signon limit isn't your issue.

I am having the same issue. Imap sessions are around 30

I've had serious IMAP issues recently & one theory is that they were triggered by malformed messages hitting several accounts. It would be worth trying a:

Code: Select all

omtidyu -M -B -u username

on an affected account. If this proves successful you can then run:

Code: Select all

omtidyallu -M

on all mailboxes (you might prefer to do this outside office hours).
