Please give more details on what kind of connection you are trying to establish (SMTP, IMAP, POP3) and how it fails.
It just doesn't seem to be using IPv6 at all (I am using SMTP and IMAP, not tried POP3) and always falls back to IPv4, even when IPv6 connection to the server available. 1) IMAP. Server is 'twin.jikos.cz'. It responds on port 143 on its IPv6 address: $ telnet twin.jikos.cz 143 Trying 2001:470:1f15:1724::1... Connected to twin.jikos.cz. Escape character is '^]'. * OK Dovecot ready. but alpine is connecting to its IPv4 address apparently: netstat -tupan | grep alpine tcp 0 0 192.168.1.102:38048 89.185.236.188:143 ESTABLISHED 18353/alpine 2) SMTP. Server is 'twin.jikos'cz again. It responds on port 25 on its IPv6 address: $ telnet twin.jikos.cz 25 Trying 2001:470:1f15:1724::1... Connected to twin.jikos.cz. Escape character is '^]'. 220 twin.jikos.cz ESMTP Sendmail 8.13.6/8.13.6; Mon, 28 Feb 2011 10:18:07 +0100 but alpine is apparently using IPv4 again, as can be seen for example in the headers of the mails sent through this SMTP server: Received: from [192.168.1.102] (ip-78-102-86-15.net.upcbroadband.cz [78.102.86.15]) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
