I'm trying to send mail via a third-party provider, but it's not working!? DSL Extreme FAQ| That's because DSL Extreme blocks outgoing connections on port 25 to prevent spam. To get rid of this problem, change the outgoing mail server on your connection to "smtp.dslextreme.com" and use your DSLX mail account login info (xxxxx@dslextreme.com) along with your password. If you'd like the outgoing 25 block to go away, go here and you can fill out the "SMTP Filter Removal" form. by Bill | ||
