Topic: How To Relay Using SME SMTP ???

[John Hadi]

I have a SME 5.5, and i used Outlook Express as my email client as well as the Webmail. The problem is that SME SMTP wont allow me to relay email (both when im in local network and outside network). This is the error message that I got:

The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'jo@axiontech.com'. Subject 'test', Account: 'mail.gtec.cc', Server: 'mail1', Protocol: SMTP, Server Response: '553 Sorry, that domain isn't in my list of allowed rcpthosts.', Port: 25, Secure(SSL): No, Server Error: 553, Error Number: 0x800CCC79

Can anyone help? Thanks.

PC's on your local network should be able to use the SMTP service without any difficulty. Standard configuration allows this by default.

Check your configuration. "Review Configuration" You should see your internal IP range defined.

You should definitely not attempt to configure your server for SMTP use when outside your own network unless you know exactly what you are doing. Misconfiguration will make it an "open relay" which will quickly be detected and used by spammers - your server could then become blacklisted causing major difficulties for you not to mention the additional traffic you will get from spam

Damien Curtain wrote some packages that implement CVM-SASL, which allow you to relay after logging on to your SMTP server.  The packages can be found here:

The easy answer to your question is when you are in your local network, don't use your domain name for the mail server, use the internal name or ip address (otherwise your sme server will see you as coming from the internet-at-large instead of from the local net thanks to routing) ;O)

Thanks for the quick fix Steve.  I use SME to host a few virtual domains and sending email has been a problem.
