mail rejected due to execssive spam
Posted on 2004-09-27
We are getting reports from someone trying to email us that any messages they send us are bouncing back to them. We are trying to determine if this is a restriction on their outgoing SMTP server, or if it's a problem with our incoming SMTP server. Here is the message they receive when they try to send us mail:
