Hi Frank,
Check /etc/courier/pop3d -- If users are coming from the same IP
address (through a proxy, masquerade, NAT, etc.) chances are courier
is hitting it's limit(s).
The config file has many, MAXPERIP for example, or MAXDAEMONS
The defaults are pretty low for a mid to large-scale production system.
Don't forget to restart the pop3 daemon after changes!
HTH.
