Hi all,
I am no Postfix master, but I have set up a mail system with postfix,qpopper and cyrus-sasl (using the sasldb2 database )on Debian Etch.
This setup is for virtual alias domains.
The sasl smtp-auth part of the setup works fine and I can send mail from say, Thunderbird, to any email address. The trouble is in receiving emails.
I believe I have set up dns correctly, but am wondering whether my problem is a dns problem or an smtp problem?
In dns, web and mail are served by separate hosts,i.e. if
I have a hosted domain say skytips.com its mail server is
mailhost.differentdomain.com.
I test smtp using telnet to a valid e-mail address, test@skytips.com which goes to the unix account test, on mailhost.differentdomain.com:
"telnet mailhost.differentdomain.com 25 etc"
(with test@skytips.com)
This works and the mail get delivered to /var/mail/test and /var/spool/mail/test
I test pop3 same thing, success, I can authenticate.
However, when I send and email from my gmail account to test@skytips.com the mail is not delivered, and I get the error message
"Error sending message.....
The reason of the delivery failure was:
Can not connect to SMTP server <skytips.com> "
Implying that the gmail server tried to connect to am SMTP server <skytips.com>.
Why is it trying to connect to <skytips.com>? The mail server for skytips.com is mailhost.differentdomain.com or at least is supposed to be?
I do not understand this, especially as the setup was working for the first few days.
Grateful for any input, am somewhat drained of energy,have not slept well for 3 days, my clients are out of mail.
My previous Sarge setup worked fine.
Best Ever
