By perusing my log files, I'm noticing that some spammers will go in
through my MX 20 record, and bypass whatever I have as countermeasures
that way. I suppose the theory is that I will always accept mail from
mx2.speakeasy.net.
On the other hand, removing the MX 20 record could be a problem in the
event of a prolonged down time. The mail theoretically has to go
somewhere, and I'd rather have it sit on a secondary mx until I come
back up, as some MTAs are configured to just bounce right away.
So as such, is there a solution I'm missing?
