Has any one had problems with mail clients were your DNS is like this;
doman.com MX 50 mail.domain.com domain.com MX 100 mail2.domain.com
domain.com CNAME www.domain.com
The short answer is you can't do that and expect it to work because you can't mix CNAME and other types of records for a hostname. It is simply an invalid configuration at a DNS level.

Forgot, i did allow this for a few weeks and mail broke as well as the wild card SSL ceasing to work as it has;
*.domain.com domain.com
At any rate, I will insist that mixing MX/CNAME will not be possible but wanted to see if I missed something.
Hence this seemingly basic posting t the list.
I think the only clean approach is to give domain.com an A record pointing to something that can run a web server that does a client redirect to www.domain.com. And even then https will show an invalid cert before the redirect unless you have one specifically for domain.com.
