And SMTP on 25/TCP.

The current setup breaks setups like

example.com	86400	IN	MX	10 mail1.xeample.com
example.com	86400	IN	MX	20 mail2.example.com

Previously, MTAs could not resolve xeample.com and would therefore use
the secondary.  Now, they can, and get a 550 error on RCPT TO:.

Granted, the setup has always been erroneous and risky, but breaking
this without proper notice is still extremely annoying.
