Often I hope gmail will get more strict and stop accepting emails for
not properly setup servers. This will would really make my life easier.

I agree with this. gmail can rcvd email from sender domain that use
IP.Add.re.ss as MX record rather than MX hostname.
While other email-related applications, like Exim and ASSP can't as they
obeying the RFC
- From: http://en.wikipedia.org/wiki/MX_record
The characteristic payload information of an MX record is the fully
qualified domain name of a mail host and a preference value. The host
name must map directly to one or more address record (A, or AAAA) in the
DNS, and must not point to any CNAME records.[1]

Thanks for this, Pak. For some time I've wondered where it's specified
that MX records must not point to CNAME records. I see now that it's in
RFC 2181, Section 10.3.
