[TriLUG] sendmail header question

[Turnpike Man]

cool... I think I'll just have to add aol, compuserv, earthlink and let the
remaining continue to use my own SMTP.  Yes, lots better to have your own
control and not have to worry about someone else's availability, queue size,
etc.

So far aol is not rejecting me, but if I were actually writing someone there
regularly, I suppose that might change!

thanks,
David M.
