I'm glad it worked. Believe me, if that simple change made it work for
you, then it was worth my headache to have spent the time to learn it
for myself ;)

For the last few years, I've only used Sendmail (or sendmail) to act as
a backup MX, or to directly deliver mail from the box I am on...hence,
it's been a while...

There may be other ramifications to using `mailertable' in your
particular environment.

I don't know how your system will react, given a default setup and a
mailertable entry.

It's possible (but untested) that if the server that is specified in the
mailertable is down, your reports might not make it to you ( whether
that's bad or good is up for interpretation... I've always known no news
as good news ;)

Perhaps Giorgos or someone else may be able to provide a better
understanding.
