Unable to send SMTP emails from Outlook when not connected to cox network.
Currently traveling and staying in a hotel for a few months. At the present time, I am unable to send email from my outlook client on two different computers or from my iPhone (wi-fi/cell).
I can send email from webmail or if I save as a draft in outlook and send from webmail. If I connect to my home router's VPN, my Outlook will send. this means that my settings are correct.
SMTP
port: 587
STARTTLS
Same authentication as incoming server (which is working.
Is COX now blocking incoming traffic on port 587 by default as a "security" measure?
