How can I be sure that SMTP authentication is really working. I have
been trying to determine is there is a reliable way of checking is my
SMTP authentication is working,
I think it is working, but as I an only test from within my own network
I am not 100% certain, Is the a tool or site that would allow me to
verify this.
To see if someone has authenticated, look for log entries
similar to:
Apr 11 14:05:33 mgate2 postfix/smtpd[18321]: C995F797865:
client=202.sub-75-254-219.myvzw.com[75.254.219.202],
sasl_method=LOGIN, sasl_username=user1
you can grep for the "sasl_method=" text.
Follow-up when I look in the my Mailllog I see this sort of thing:
Apr 11 15:17:51 localhost postfix/smtpd[26037]: Anonymous TLS connection
established from unknown[192.168.10.25]: TLSv1 with cipher
DHE-RSA-AES256-SHA (256/256 bits)
which makes me think that it is working, however is it normal for the
connection to be "anonymous"?
This shows a successful TLS connection. Postfix doesn't ask
the client for a certificate, so all connections will be
logged as "Anonymous" - this is normal.
