Summary: Sending e-mail via the SMTP transport with IPv6 is
Platform: OpenBSD Packages
AssignedTo: kdepim-bugs kde org
ReportedBy: brad comstyle com
Version: (using KDE 3.5.9)
Installed from: OpenBSD Packages
Compiler: GCC 3.3.5
Configuring an SMTP transport to use a FQDN which has an AAAA DNS record results in KMail attempting to connect to the SMTP server and immediately disconnecting with a dialog box popping up saying "Sending failed: The process for the smtp://[server name] protocol died unexpectedly" and the message is not sent. If I configure the SMTP transport with the IPv6 address KMail does not even attempt to connect to the server and fails immediately with an error message of "Sending failed: Could not connect to host [IPv6 address]".
The server side shows the following for the initial connection described above...
Apr 3 00:31:06 speedy postfix/smtpd: connect from booyah.home.comstyle.com[2001:470:8802:3:216:41ff:fe17:6933]
Apr 3 00:31:06 speedy postfix/smtpd: lost connection after CONNECT from booyah.home.comstyle.com[2001:470:8802:3:216:41ff:fe17:6933]
Apr 3 00:31:06 speedy postfix/smtpd: disconnect from booyah.home.comstyle.com[2001:470:8802:3:216:41ff:fe17:6933]
POP3 and IMAP work fine for retrieving e-mail from the server. Other MUAs with IPv6 support are able to send mail via this server and with IPv6 in general.
