Hello all,

I am attempting to install 4.0.3 on my home network under Debian. I did a test install of 4.0.2 a few weeks ago, but am ready to tak the plunge. I am encountering a couple of problems though...

First of all, the installer is telling me

DNS ERROR resolving MX for merrimac.foo.yi.org
It is suggested that the domain name have an MX record configured in DNS
Change domain name? [Yes]
Now as far as I can tell, I have the DNS wired seven ways to Sunday:

# dig mail.foo.yi.org

mail.foo.yi.org. 86400 IN CNAME merrimac.foo.yi.org.
merrimac.foo.yi.org. 86400 IN A
# dig MX foo.yi.org

foo.yi.org. 86400 IN   MX      10 merrimac.foo.yi.org.
foo.yi.org. 86400 IN   MX      12 mekong.foo.yi.org.
So I have a valid A record for merrimac, a CNAME record to mail.foo.yi.org and a valid MX record. Why is the installer still telling me that it cannot resolve the domain name?

The other thing is where do I set the domain on the install? Since this install is for my home network, I don't want the default mail domain to be merrimac.foo.yi.org, I want it to be foo.yi.org. Where does that get set during the install? And would it be better to not set a maildomain of merrimac.foo.yi.org at all?
