I guess they got on the security bandwagon. But I logged into my Cisco firewall and realized I’d not been getting log emails from it. Saw six errors – all to do with could not connect to Cox’s SMTP.
Then I remembered – I don’t use Cox email anymore. But someone does and I had to change it in Thunderbird but didn’t think to change the firewall.
SMTP went from the standard port 25 to 587. No idea what POP went to though as I don’t use it.
Plus they’re enforcing login for SMTP now. So I changed the setting on my firewall and am now getting emails from it again.
