Uverse Blocking SMTP port 25

Currently having this same issue on Port 25. Have ran a myriad of tests, spoke with a few U-Verse representatives. Would like to get this resolved as our business is currently unable to function without outbound port 25 open.

Not everyone knows how to use a different port or what ports are available. Port 25 is the default, so many people are seeing this issue. It would be helpful to mention changing the port as a free option, and it would be great if there was some documentation available.

I use Windows Mail, and I had the same issue -- trying to send email over default port 25, which is blocked. To resolve the issue, I switched to port 587, which seems to be working just fine and did not cost extra. I got the idea to switch to port 587 from this Windows forum.

I hope this helps others quickly resolve the issue on their own with no extra charge.

Screenshot below shows where I changed my setting in Windows Mail. Go to Accounts > Properties > Advanced. Manually type in a different port number. 587 seems to be working for me, which I got from the Windows forum linked above.

I tried calling customer service to get my Port 25 opened. They could not help and wanted to send me to advanced customer support and charge me $49!

Try switching your mail client to use a different port. Port 587 is a common alternative SMTP port. How you change ports depends on what mail client you use (e.g. Windows Mail).
