Αντικείμενο: RE: [Exim] Help please : SMTP Relay Messages Frozen
Hi,

Is no one able to help ? I try and try but it seems like I don't understand
why Exim refuses to deliver my outgoing emails while the locals work fine :(
Someone please help. I attach the complete debug information now I hope this
is not against any rules here.

Best regards,

-Alex

Hi Dominik,

Thanks for the tip I just did what you said but I must admit I am lost with
the debug output and it is so much info that I don't want to post it here. I
am not very experienced with exim I did use sendmail all the time but heard
that exim is very good so I thought I switch but currently it looks like I
have to setup sendmail again at least I know there how to send mails :(

Btw I did check the logs of the server I want to send the mail to and the
logs there show nothing so at least I know the mail never left the server.

Best regards,

-Alex

Hi Alex,

you should run exim directly from the command line with debugging turned on.
see section 5.3 of the exim specification under
http://www.exim.org/exim-html-4.20/doc/html/spec.html
for all the command line options.

Example:
$ cat smtp1
HELO localhost
MAIL FROM:<local_address>
RCPT TO:<remote_address>
DATA
From: <local_address>
To: <remote_address>
Subject: test from localhost
.
QUIT

$ cat smtp1 | exim -d+transport -bh localhost
...a lot of debugging output...

From that output you should be able to tell more exactly
what could be the problem.

BTW. why did you specify the user option for the *transport*?
The specification clearly states
> *user*
> [...]
> For remote transports, you should leave this option unset unless you
> really are sure you know what you are doing. When a remote transport
> is running, it needs to be able to access Exim's hints databases,
> because each host may have its own retry data.

(in chapter 23. Generic Transport Options)

dominik
