Postfix Mail relaying config Fedora 4

[fatlip]

Hi there,

I used this tutorial (http://www.howtoforge.com/linux_spam_filter_mail_gateway)to set up a spam and virus filtering mail gateway on Fedora 4 core. The tutorial was great, but I am have some issues with relaying to appropriate domains.

I have the following in main.cf

relay_domains = domain1.com, domain2.com
transport_maps = hash:/etc/postfix/transport

and my transport file:
domain1.com smtp:[192.168.123.31]
domain2.com smtp:[192.168.123.31]

Domain1 works pertfectly fine, no issues whatsoever.

Domain2: you can telnet to the server and send mail to it no problem. If I try and send from any mail client(gmail.com for one) I get a 550 relaying denied bounce.

I am sure you can see why I am a little baffled! I am using a different external connection to telnet in than the internal network, so I know it's not any sort of allowed subnet issue.

I am VERY new to postfix, but any guidance would be greatly appreciated!

Thanks,
Greg

What's in your mail log when this happens?

Problem fixed. Was DNS related.

Thanks,

One more thing.. can someone direct me to where I can set either postfix, or Mailscanner to delete suspected spam instead of just modifying the subject line of the e-mail? I have googled away, but most of my findings all relate back to Webmin, which I don't use as I am a command line guy.

Thanks in advance!
Greg

I've never worked with Mailscanner... Isn't this adjustable in the Mailscanner configuration file?

Thanks Falko,

I did get this figured out as well. It is in the MailScanner.conf file, WAYYY at the bottom.

Thanks Again,
Greg
