Max Number of connections per IP (Email)

Seem to be having some problems when having more than 5/6 email accounts open, get errors when Sending/Receive (random: dependent on which account hits max limit) - does anyone know how to up that Max number to something like 8/10?

I would think this is a bug in Plesk as, it should automatically 'calculate' max number of open connections per IP depending on email accounts created. But then again not allof us have 8 email accounts, I guess!!

Your help would be muchly appreciated, many thanks!

For IMAP, in /usr/lib/courier-imap/etc/imapd file, find out what MAXPERIP is set to. Increase it to whatever you want. Plesk sets it to 4.

Similarly for pop3, in /usr/lib/courier-imap/etc/pop3d file, find out what MAXPERIP is set to. Increase it to whatever you want. Plesk sets it to 4.

I haven't faced any problem while sending email and dont' know how to change it.
