I'm trying to configure postfix for SMTP Auth using Cyrus saslauthd and an rimap configuration. I have it working, except for the fact that, due to virtual domains, the auth username for my IMAP installation uses full email addresses (foo@example.com), but postfix (or perhaps saslauthd?) is removing the domain name when sending the auth request to the IMAP server.
From /var/log/mail.log:
May 7 10:54:02 xxx postfix/smtpd[25564]: warning: SASL authentication failure: Password verification failed
May 7 10:54:02 xxx postfix/smtpd[25564]: warning: 108-71-0-101.lightspeed.lsvlky.sbcglobal.net[108.71.0.101]: SASL PLAIN authentication failed: authentication failure
May 7 10:54:02 xxx imapd: Disconnected, ip=[::ffff:127.0.0.1], time=5
May 7 10:54:02 xxx imapd: Connection, ip=[::ffff:127.0.0.1]
May 7 10:54:02 xxx imapd: LOGIN FAILED, user=foo, ip=[::ffff:127.0.0.1]
Notice on the last line, LOGIN FAILED, user=foo, and not foo@example.com.
I have verified that my saslauthd is working with the full address from the command line:
# testsaslauthd -u foo@example.com -p abc123
0: OK "Success."
# testsaslauthd -u foo -p abc123
0: NO "authentication failed"
Is there any way to use the full email address here?
