outbound SMTP email failing
I know there have been many posts on this, but I can't seem to get resolution in spite of my reading them.
Have AT&T uverse Internet
Could not send outbound aol email at all. Could receive fine.
Read the existing posts about port 25 being blocked by AT&T uverse.
Called and had tech support unblock port 25. All was fine for one day.
Now, email is suddenly intermittent. Outbound email to smtp.aol.com does not work reliably.
Performed this "telnet test":
- telnet outbound.att.net 25
get the response:
- Connecting To outbound.att.net...
- 220 smtp.mail.att.net ESMTP ready
which appears to indicate port 25 is open, correct?
Any suggestions on what might cause the problem?
Are there other workarounds? Should I / could I use a different outbound SMTP server?
thanks in advance,
