Well, it may be a moot point as they have decided to just go with Network
Solutions for everything, but I am still curious why Courier was bouncing
apparently valid e-mails.
The MX and the A records were configured correctly. I have setup a template
that I copy and modify the relevant portions when I'm adding a new domain.
In this case I had to change the A record for the main domain and for the
www. and ftp. sub-domains to another IP. The MX and the A record I setup for
the mail. sub-domain, however, were pointing to my server.
There is only one MX record, and it reads like this:
IN MX 10 mail.domainname.com.
Then the A records read like this:
domainname.com. IN A 123.123.123.123
www.domainname.com. IN A 123.123.123.123
ftp.domainname.com. IN A 123.123.123.123
mail.domainname.com. IN A 111.111.111.111
