TICKET ARCHIVE -> Mac Email Problems

Magnolia - Aug 2, 2005 - 9:37 am

We are having emails returned from the following ISPs: AOL, JUNO, and RoadRunner. This is the preliminary message we receive:
"Unable to deliver message to the following recipients, due to being unable to connect successfully to the destination mail server."

We have our own Exchange email server, and we have only one MAC on the network. The MAC is having trouble sending email messages to all three of these ISPs.

Any thoughts?

Thank you!

Try this:

telnet mailin-02.mx.aol.com 25

You should get a response that looks like this:

If not, it may be a network issue. If you can, you may be blocked from sending emails for some reason.
