Excellent question and unfortunately I don't have an answer. I will run
that one by management as it is an obviously great idea now that you
mention it.

We also support SSL access for SMTP and POP, so that could be a
possibility as well.
I appreciate the feedback on this from everyone. I'm still not 100%
convinced that a blanket port block is the answer, but then again I'm
not an ISP so my opinion shouldn't be on the top of the list of
considerations either. I do have some things to think about for new
customers though <g>.
