Topic: Send mail from virtual domain?

[Andrew Taylor]

Hi,

We have a DSL connection for a small office, the DSL is connected to a firewall/router combo. I have an SME box which we use for IMAP and SMTP. My local domain is defined as 'local' the server is 'mail'. So the FQDN for the primary server (in SME) is mail.local. I have added a virtual domain 'mydomain.com'. Using mult-drop I can successfully send e-mail to andrew.taylor@mydomain.com, it goes to my ISP's POP3, we collect it using the SME box and it gets distributed to the local user 'andrewtaylor' imap folder.

This all works fine, we can also send e-mail via the SME box directly to the receiving SMTP server (not via the ISP mail server).

However, when ever I send e-mail the headers show the connection coming from mail.local (192.168.1.1).

I've noticed this question posted on the forum before, where the user was concerned for security, this doesn't bother me as I don't see any security risk, however, I've noticed some e-mail servers doing a DNS lookup on the hostname and refusing to accept the e-mail as the name (server.local) obviously isn't resolving.

Am I doing something wrong??

Thanks

Andrew
