Important Information for SBC Yahoo! DSL customers

If you are having problems sending mail through MMA's SMTP mail server and are an SBC Yahoo! DSL customer, this is due to a new "Port 25 Filter" that SBC has started implementing for its DSL customers.

The "Port 25 Filter" essentially blocks sending SMTP mail using Port 25 for all mail servers other than SBC's SMTP server. While this is a good thing overall, as it will mean less spam and malicious email messages being sent via SBC's DSL accounts, it has resulted in some MMA customers being unable to send mail using current configurations.
