Uverse is blocking my outbound SMTP email on port 587
I have my own exchange server using Exchange 2016. I have configure it to use port 995 for inbound and 587 for outbound using TLS. I am now having issue sending email but have no problem receiving. I had check and double check my settings, check my Firewalls and including using Telnet which show that I am being blocked. Anyone having this issue and what was the resolution? Thanks in advance for any help.
