Major potential e-mail problems is one reason I am weary of using
RainConnect if that is what you are using.
I am very busy this week including waking up to a down server today, but if
you continue to have problems please describe again your exact configuration
including real domain names and IP addresses and I will review it. If you
would rather, send me the information off list.
