I cannot use my Optimum Online Email Account on Mail anymore. Cablevision said the modem was working properly so it must be an Apple issue.

This is the error message I get:

Connection Failed

There may be a problem with the mail server or network. Check the settings for account or try again.

The server error encountered was: The server cannot be contacted on port 110.

Any ideas?
