UNIX for Dummies Questions & Answers

Hi

I have a working sendmail setup for my domain, but would like to run a subdomain on another machine. I could try below, but its a production server and worry about messing it up. Hence the question.

So I have machine names:

mydomain.com (mail server)
dev.mydomain.com

currently the MX record points to mydomain.com
Can I add another MX record for dev.mydomain.com which points to the same - mydomain.com, ie

mydomain.com. IN MX 0 mail.mydomain.com.
dev.mydomain.com. IN MX 0 mail.mydomain.com.

That way both mails get redirected to mail.mydomain.com for handling. OR is it better:

dev.mydomain.com. IN MX 0 dev.mydomain.com.

I want both domain emails to go to my main machine mail.mydomain.com.


Thanks.

If you add the subdomain MX, it will go there, but still the rewrite rules in your mail server may want to reject or discard it. Try and see.

If you send it elsewhere, you can rewrite it and forward it to the prod server.

Make sure dev test messages do not get prod people upset! Maybe rewrite the subjects with a prefix or something?
