I've seen this question asked a million times but not answered.
In a foreign country (the Netherlands, Belgium, the Czech Republic, Italy, ...)
Connected via WIFI or 4G, doesn't matter.
Sending from an IMAP client (tho' the outgoing server is smtp.cox.net, is there any other option?) on my android, the mail sits in the outbox saying failed. Returning to the states, the email sends.
Using webmail.cox.net (redirects to idm.west.cox.net/coxlogin/....blah blah), I get a capcha (click I am not a robot) followed by a required entry of last 4 of SSN. Sending an email here fails with
Message could not be sent....
(550-550 184.108.40.206 blocked ....)
I understand that Cox bluntly blocks seemingly all foreign IP to prevent spammers and I can request a white list on an IP, but that's not a workable solution as I move from location to location. Is there a method that allows me to confidently use Cox email overseas on my android or am I forced to another email service?
The cox error msg CXBL says the "sending" address is being blocked because it is an abusing address.
Sure enough ... if you do a web search on 220.127.116.11 ... several web sites report 80 or 90 abuses from that address.
But i am being blocked from sending from Portugal ... a 79.xxx.xxx.xxx address ... not a 146.xxx.xxx.xxx address.
I am not doing anything wrong. It looks like some software in use by cox is routing my mail attempts thru the 146 address.
This looks like something cox has to fix. We users are powerless to fix this.
