- locate the imapd process serving your connection (using ps, netstat etc) - attach a strace to it: # strace -f -p <pid> - see what system calls it is making - post that information here If you can replicate this problem using telnet to port 143, and manually issuing the examine/select, then it will be easier to debug: you can attach the strace process after logging in but before issuing the examine/select, so you'll see the whole set of operations. I suspect that either it's hanging on some I/O operation, or else it's livelocking for some reason (doing the same thing over and over again), but without the strace information I can't think why it would be doing so. When you say "POP3 works fine" is that using courier's pop3d, or something else (e.g. qmail pop3d)?
