Hello everyone! I have successfully set up a perdition server which acts as a proxy to pop3 servers running in virtual machines. I use the pop3s protocol to get the emails. I can get mail using Thunderbird in Linux and Outlook in Windows, however Outlook.com and gmail.com cannot communicate with the perdition server: Please take a look at the perdition log file: perdition.pop3s[15859]: Connect: 65.55.41.7:58616->X.X.X.X:995perdition.pop3s[15859]: SSL connection using AES256-SHAperdition.pop3s[15859]: SELF: "+OK POP3 perditon ready on X.X.X.X 0002937a\r\n"perdition.pop3s[15859]: CLIENT: ""perdition.pop3s[15859]: token_read: token_fill_bufferperdition.pop3s[15859]: read_line: token_readperdition.pop3s[15859]: pop3_in_get_auth: read_lineperdition.pop3s[15859]: main: protocol->in_get_authperdition.pop3s[15859]: Fatal Error reading authentication information from client 65.55.41.7:58616->X.X.X.X:995: Exiting child It seems that the SSL connection works (SSL connection using AES256-SHA) but Outlook.com and gmail.com are not able to authenticate. Outlook.com works fine when connecting directly to dovecot but fails when going through perdition. Thanks in advance for any help you may provide.
