Andy,

How can I tell? I have 'proxyservers: yes' set in /etc/imapd.conf (and
restarted cyrus), I use sasl-authd to talk to my openldap back end. How
do I tell if this is proxy or not? Reading the logs I see lines that
read 'Aug 18 15:20:24 $HOST imap[6567]: login: localhost [127.0.0.1]
cyrus plaintext User logged in' when I log in using 'imtest -u $USER -a
cyrus localhost'. I think I'm using PLAIN.
