Re: [Dovecot] Differences between IPv4 and IPv6 authentication

If I do an SSL connection I get only this for external IPv6: 2010-11-02 02:51:38 imap-login: Info: Disconnected (no auth attempts): rip=178.63.10.79, lip=188.40.178.56 Those are IPv4 addresses, so if you really were connecting with IPv6 something changed it to IPv4 in the middle. I'm afraid that still leaves me stumped. Any further suggestions? Are you sure IPv6 works at all in the server? Or maybe it has firewall settings to disallow imap port for IPv6. Anyway, the problem clearly isn't with Dovecot.

I assumed that the same authentication mechanisms would be used, regardless of the protocol being used - are there differences somewhere? No. ~$ telnet server1.teststable.simplyspamfree.com 143 Try 127.0.0.1 vs ::1 Any insight would be appreciated, thanks! Proxy/firewall/antivirus/etc in the middle? If none of that is helpful, set auth_debug_passwords=yes and see the logs.
