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

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

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