I don't think so. I just added the hostname to the server /etc/hosts file and it made no difference. And the failure is a hang instead of a useful error message, which I would expect from an active rejection. I did run saslauthd with "-d" and found it produced no ouput when I tried sending mail. So it seems to me that Postfix smtpd is never successfully contacting saslauthd. I did try turning on TLS logging, but that doesn't seem to help. I don't *think* the problem is in TLS. >I'll take a stab in the dark and guess that maybe your main.cf doesn't >have the value for mynetworks set like this: > >mynetworks = 192.168.1.0/24 > >This specifies that any system in this subnet is allowed to connect the >postfix server. I did not have this before. I do not believe this feature is useful in my setup where I want to be able to relay mail remotely (i.e.: Not on the local net). I depend on sasl authorization alone for relay access. -dl _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
