SMTP problem

Have not been able to get SMTP to work on 1 account.  All settings OK.  Checked and rechecked.  Can’t send mail unless I change port to 25 which is not specified.  Should be 465 or 587.  Does not like either.

For port 465 make sure the security policy is Use SSL/TLS on special port (legacy)

It is and always has been.   Username and password have not changed recently.  Maybe I should change password on mail server.

You could try that. Who is your email provider?

The best port is 587, with Force usage of SSL/TLS.

I just had a problem with my smtp link with Comcast: this fixed the problem!
