I hate to state the obvious, but yes, it is obviously a problem with
DNS. Sure, the hostname resolves fine, but your DNS does not return an
MX for it. See results below:
[andy@mail andy]$ dnsmx qmail.mainstream.net
dnsmx: fatal: unable to find MX records for qmail.mainstream.net: temporary failure
This should, in the very least return a preference of 0 for the server
itself. Instead it is failing---something is misconfigured in your
DNS. The same results can be found with dig:
[andy@mail andy]$ dig qmail.mainstream.net mx
; <<>> DiG 8.1 <<>> qmail.mainstream.net mx
;; res options: init recurs defnam dnsrch

;; QUERY SECTION:

Please, someone correct me if I'm wrong, but I do believe it is a
problem with DNS. :-)
