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.

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.
