IMAP works, but no SMTP (for sending mail) SOLVED

Wed Feb 16 18:01:08 EST 2005

Thanks for the detailed information aboute to use AUTH LOGIN, but I now found out, whats the problem is.

Here we go:
For SMTP authentication don't use /usr/lib/sasl2/smtpd.conf

NOTE:
YOU HAVE TO USE /etc/sasl2/smtpd.conf and insert the following line:
Code:

pwcheck_method:saslauthd

Restart the needed deamons
Code:

/etc/init.d/postfix restart
/etc/init.d/saslauthd restart
/etc/init.d/cyrus restart

Now it will works. Fine

Thx,
Benjamin
