I have a new Exchange org, created 2 mail-enabled public
folders, both have valid SMTP addresses. I am getting
bounce-backs when trying to send external mail to these
folders, saying that the message got to my server but
delivery was refused. The folders do receive mail that
originates internally (non-SMTP) and SMTP mail flows fine
to individual mailboxes outside the public store, so I
don't belive it to be an SMTP connectivity issue.
Anything I'm missing here?
