Solution
Open your Courier-IMAP configuration file; on Debian it’s /etc/courier/imapd:
vi /etc/courier/imapd
Adjust the MAXDAEMONS and MAXPERIP settings (you might have to play around with these values)…
[...] ##NAME: MAXDAEMONS:0 # # Maximum number of IMAP servers started # MAXDAEMONS=40 ##NAME: MAXPERIP:0 # # Maximum number of connections to accept from the same IP address MAXPERIP=20 [...]
… and restart Courier-IMAP – on Debian this can be done with:
/etc/init.d/courier-imap restart
