Does anyone have contacts at Charter (Spectrum) and Cox? For some reason,
our IP has been blocked by them and our customers are unable to send email
via their charter/cox accounts. Thanks
Would you be talking about port 25/tcp outbound? Lots of ISPs will
block port 25 as a rule; you have to call to have it opened. At the
same time, you can request the PTR record you need to keep big mail
It's the outgoing smtp ports, 587 for charter and 465 for cox.
They are open on my end but our IP address that most of our
customers are natted through is blocked by the email servers.
