Summary0001451: mail addresses

Reported by dastrath, but translated by me:

"Support regularly received mails from IANA that a mail has been sent to 192.168.x.x. Every time this happens an IANA ticket is created, which is then closed after a few days."

First of all there should be some research if it is possible to provoke mails to be sent to RFC1918 mail addresses on the testsystem. Maybe this can happen during registration of a new account, or by trying to add an IP-address as a domain.

IP addresses should not be accepted as domains at all. I'm quite sure that this is already handled, but I did not test. So, use your imagination and try to get the testsystem to accept (or at least, send a probe mail to) an IP address!
