Earthlink SMTP smtpauth.earthlink.net outbound email being blocked?

I work for a small business & we use Earthlink SMTP smtpauth.earthlink.net outbound email service to function. The software worked flawlessly until I changed from cable to U-Verse. Does anyone have any answers for this problem. Uverse appears to be blocking the SMTPserver port. I am inclined to agree since things have not been a problem until the new service was set up from ATT.

I located this on Earthlinks site:

I can receive email, but not send it. What should I do?

Check to make sure that your email program has the outgoing (SMTP) sever set up correctly.

The Outgoing SMTP server should be smtpauth.earthlink.net (same for all email addresses)
Put a check in the box for “My Outgoing SMTP server requires authentication” (or something similar) and enter your entire email address and password for authentication.
Set the Outgoing SMTP port number to 587. This is usually found under your email software’s Advanced Account settings section.

I assume you can receive but not send?

If you do as the instructions provided by BeeBeeSA suggest, you will not be using the default SMTP port (TCP 25) to transmit and will thus work around the block of TCP 25 that AT&T places on U-verse lines by default (as an anti-SPAM/anti-malware measure).

This is the best way to resolve this issue.
