Spam Domain Check

[m1byo]

Would it be possible to include an option to check whether an external sender domain exists.

I can see it is possible to do it for internal domains, and the SPF check does a similar job except not all domains have SPF records, especially if the domain doesnt exist!

Thanks

Thank you for the suggestion, I have forwarded this to the rest of the team. Up until now we have avoided this due to extra work load involved in verifying the account. However, on mail servers that have low levels of incoming mail, this would certainly help protect against SPAM.
