We have been seeing problems with Couriers POP service. Really ever since switching from CPPOP. The fact that you can set the maximums on Couriers services seems good. However this also seems to inhibit proper functioning and tracking of problems when they arise. We have been seeing pop3login hitting 300 - 400 processes, however they never seem to terminate and seems to clog up the POP 3 server causing timeouts. We have tried changing the pop3 server limits really high and even low but always the amount of pop3logins hits the max set. Can anyone provide me assistance on how to deal with Courier and these problems or does anyone know of an alternative to Courier that will work with Cpanel and better for a busy POP server?
