I don't see any references to tls in your postconf -n output. Has postfix been built with openssl?
I guess so. 'ldd /usr/sbin/postfix' gives, amoung others:
libsasl2.so.2 => /usr/lib64/libsasl2.so.2 (0x00002b71e8eea000)
libssl.so.6 => /lib64/libssl.so.6 (0x00002b71e9103000)I did not put any 'tls' options into main.cf (nor the -o smtpd_tls_wrappermode option in master.cf) as the postfix/dovecot/SASL howto on dovecot's wiki does not mention it at all. So I thought that TLS is not required to make SASL authetication. Am I wrong?
I have actually enabled the smtpd_tls_wrappermode option for a while while trying to make it work but it resulted in immediate postfix failure (probably this would require other tls options enabled, too), so I backed off.
I have the SMTP outgoing server in T'bird set to SSL which makes the default port 465 to be used. When I change this to TLS, the default seems to be the "plain" port #25.
Also, postfix 2.3 is quite old, for a new installation consider a more recent version.
Well, that may be worth trying but I guess (as it has already happened with dovecot update from 1.0.6 to 1.1.16 version) that, although it may be a good idea in general, it will not help with my current problem. I think that properly configured postfix/dovecot (in versions generally available for RHEL/CentOS 5.3) should work with authentication.
