They also told me that Mediacom uses Spamhaus to cut down on spammers. When I talked with a Mediacom tech support person last year (over the phone) I told them about this Spamhaus error message and they checked my account and said they do not see any unusual activity that would lead them to believe that I am spamming anyone.

Plus what kind of a spammer would only send out 4 spams in 28 days? Spamhaus does have my IP listed on a CBL list as a spammer but the test showed 4 episodes in the last 28 days and one of those was in the last 24 hours (which was impossible as my VPN has not been shut off for several days as that is the only way I can sendĪny emails). (The 50.xx.xxx.xx-I blanked out part of my IP address since this is public) "The server responded: 554 njtocomv01 Mediacom HjkYjLnloTS0P POL106 Connection Rejected - see ESMTP server not available". "The server responded: 554 njtocomv01 Mediacom I19KjOme9TS0P POL106 Connectio" The error messages I get vary between "The server responded: 554 mc-obgw-5002a Mediacom I1S0jSRsTsjiL POL106 Connec" I have checked and all my settings are still correct according to Mediacom's recommended settings for Outlook and my cell phone. I can send Mediacom emails through my Verizon service on my phone just fine but cannot send them when connected to my Mediacom wifi with my Mediacom IP address. I can send gmails from Outlook through my Mediacom IP address just fine. If I search around and find a VPN address that works I can send my Mediacom emails through the VPN address. Then I started having issues of not being able to send email with my Mediacom email addressess while connected to my Mediacom IP address. Outlook used to work just fine with Mediacom up until about a year ago. That Outlook is giving back but they refuse to take any ownership of the problem and tell me to use their webmail (awkard, time consuming, and not efficient like my Outlook) or contact Microsoft as it is not their problem. I have been going round and round with Mediacom TotalCare (isn't that term an ironic term as they don't care at all) about not being able to send emails with my Mediacom email addresses over my Mediacom IP address.
