Try using ptrace/strace on the processes in question - it can often tell 
you where they're being held up - DNS lookup, opening a tcp connection, 
etc - and give you a good line on what to investigate.

"man imapd.conf" has more info on debugging cyrus using strace/ptrace; 
when it comes to your MTA you'll need to find that out separately.

I use this debug command in my imapd.conf:

debug_command: /usr/bin/strace -tt -o /tmp/strace.cyrus.%s.%d -p %2$d 
<&- 2>&1 &

which is from somewhere in the Cyrus docs.
