I'm working on getting a Murder setup and I can authenticate and pull mail directly from the backend server.
However, when I try to proxy the connection I get this in /var/log/messages on the proxy/master: Jan 31 13:40:35 zeus pop3[5437]: login: SERVER[192.168.247.241] hbeatty plaintext Jan 31 13:40:35 zeus pop3[5437]: couldn't authenticate to backend server: no mechanism available Jan 31 13:40:35 zeus pop3[5437]: couldn't authenticate to backend server I get this in /var/log/imapd.log on the backend server: Jan 31 13:45:01 draco pop3[32718]: accepted connection Jan 31 13:45:01 draco master[32724]: about to exec /usr/cyrus/bin/pop3d Jan 31 13:45:01 draco master[32688]: process 32718 exited, status 0 Jan 31 13:45:01 draco pop3[32724]: executed With this in mind it would seem that when using the proxy the authentication method is different somehow. Is this correct?
