After changing ISPs, I had to change settings on the smtp connector on the virtual server to get emails to flow out. I reran the CEICW once the ISP changed. The mail record was also forwarded to the new static IP. Incoming email has not been an issue.
I had to click "Use DNS to route to each address space on this connector" and to "allow public folder referrals". Before I had "forward all mail through.. smart host" . When I changed it to the new static IP from the ISP, outgoing email was returned by the system administrator - "you do not have permissions". The connector went to "retry" status. What do I need to look for?
