Understood.

Also understood, with one qualification: understanding that Comcast
has no obligation to not change my IP address, the fact is that they
HAVEN'T changed it for quite a long time.  Again, that does not mean
that they won't change it while I'm typing this email, it's just to
say that they HAVEN'T changed it for a very long time.

Again understood.  But that has not been the case with my situation,
since in fact my IP has not changed.  So if I can assume that if my IP
address doesn't change that my mail will be delivered to me
successfully, then that would account for the fact that up until VERY
recently this admittedly fragile setup has been working like a charm.
No guarantees that it would continue to work of course, just stating
that it HAS worked for a very long time.

Slightly off of the thoughts stated above, but I have a free DNS
account with dnsexit.com.  So in rare situations where my IP address
does change I just change my IP address at dnsexit.com and everything
is back to normal.

Anyway, if you have any more thoughts based on my above reply, I would
love to hear them.

Thank You,
