I am running I-Mail 8.05 on our mailserver.
There are a couple of people that we do business regularly with but we cannot send them e-mails. E-mail messages that we do send to them immediately are bounced back to us as 'undeliverable'.
One of the techs that works for one of these businesses said that our server is not configured to 'accept incoming error messages'... I can't seem to figure out what setting this is, or how to change it.
Does this make sense to anyone?
Thanks in advance.
