Please consider adding dovecot (IMAP & POP binaries) to the stock-default LFD process ignore list; this will help to limit the [e-mail log "Spam"] that is triggered by simple IMAP and POP usage.
May want to consider:
/usr/local/libexec/dovecot/imap
/usr/local/libexec/dovecot/pop3
/usr/local/libexec/dovecot/imap-login
/usr/local/libexec/dovecot/pop3-login
/usr/local/libexec/dovecot/dovecot-auth
/usr/local/sbin/dovecot
Which are the paths for a source install of dovecot.
