DNS - mail relay error


Hey



I am hosting a DNS server at my office. When one of my clients enter information on the website and click on send they are presented with the following error:

--------------------------------------------------------------------
Persits.MailSender.4 error '800a0004'

Connection refused.

/save_comments.asp, line 45
--------------------------------------------------------------------

When they click on send, the form they are sending is suppose to go to my email address.

I know this is a mail relay error, but I dont know anything about it.

Please HELP urgently.

Thanks in advance
Wazza

Take a look at /save_comments.asp, in the vicinity of line 45. Doesn't it contain any clues on what's going on?
For instance, how is the mail sent? By establishing an SMTP connection to a mail server? If that's the case, then some firewall may be blocking port 25 (SMTP) access for your web users.

If instead it's using a program like sendmail or /bin/mail to send out the mail, then you may need to check their configuration too.

So, first goal would be to find out to what e-mail address/server the mail is sent to and via which mechanism (direct SMTP connection or some program/mail queue).

Hey again

I have checked the firewall settings. Nothing is blocking it. Port 25 is open.

This error has something to do with mail relaying and the postfix folder. I have tried adding the file relay domains to the postfix folder, but sadly no success.

Thanks

What does the mail log (in /var/log) report? If postfix accepts the mail, but can't relay it, then it should print some message in the mail log.

Since we weren't given much info to go on, I am assuming that you are running a web site that has a page that enables a visitor to send email to someone else. And that this web server passes on this mail to a mail server. And you say that you are also hosting a DNS server. So, first, how many of these servers exist on the same host? Are they three different machines? Are they all on the same subnet? Are some remote to your site, etc? Please give us some more info on the specifics of your set up to enable a more accurate diagnosis. Thanks!
