We use the following on Linux, where fork() is cheap:
imap cmd="imapd -U 1" listen="imap" proto="tcp4"
On other platforms where fork() is more expensive, you'll want to set -
U higher to save on fork() overhead.
We also wanted to use -U 1 so we could be sure changes to imapd.conf
would be used more quickly since there wouldn't be imapd procs hanging
around with old settings.
