I'm having an issue with inbound email flow to my organization. Emails work fine outbound no problem, but emails inbound seem to be getting delayed from external email addresses, such as yahoo and hotmail.
This is the error message from hotmail.
This is an automatically generated Delivery Status Notification.
Unable to deliver message to the following recipients, due to being unable to connect successfully to the destination mail server
This is the error message from yahoo.
I'm afraid I wasn't able to deliver your message to the following
addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
<user@company.com>:
Connected to 75.xx.xx.xx but connection died. (#4.4.2)
I'm not going to try again; this message has been in the queue too
long.
On the firewall, i've let any port 25 traffic go to the Exchange 2003 server.
Anyone have any ideas on what other troubleshooting i can do on my side? Thanks.
