Have a look at /etc/cyrus.conf: SERVICES { # --- Normal cyrus spool, or Murder backends --- # add or remove based on preferences imap cmd="imapd -U 30" listen="imap" prefork=0 maxchild=100 imaps cmd="imapd -s -U 30" listen="imaps" prefork=0 maxchild=100 # pop3 cmd="pop3d -U 30" listen="pop3" prefork=0 maxchild=50 #pop3s cmd="pop3d -s -U 30" listen="pop3s" prefork=0 maxchild=50 #nntp cmd="nntpd -U 30" listen="nntp" prefork=0 maxchild=100 #nntps cmd="nntpd -s -U 30" listen="nntps" prefork=0 maxchild=100 Just hash out imap and restart cyrus.
