Hi, I've got a problem with dovecot regarding a pop3 proxy issue. When I configure a dovecot server to do just plain pop3 I can telnet from a windows box without any flaw, but as soon as the client uses some pop3 proxy (for example outlook uses avira antivir Mail-AntiVirus Protection), queries to that server fail. A log line looks like this:
pop3-login: Dec 05 22:53:24 Info: Disconnected [::ffff:84.165.54.42]
Moreover with the proxy activated, a telnet to port 110 (pop3) is not working properly, the cursor stays right behind "+OK dovecot ready." and as soon as I enter a character, the server rejects this character as an unknown command. As soon as I turn off the Antivir-Proxy the telnet to port 110 runs flawlessly and I can login. Is there any fix for that? Or did I misunderstand something? TIA for any hint
Regards, Michael
