A customer's email is being rejected by gmail with the following codes:
Action: failed Status: 5.7.0 Diagnostic-Code: smtp; 554 5.7.0 Reject, id=17756-61 - SPAM
I see the A record for the domain, GoDaddy's web server at 126.96.36.199 is blacklisted (info from mxtoolbox.com). I would assume because some site on it is infected by malware.
GoDaddy is telling me this has nothing to do with email delivery, but that they will get the server off the blacklists anyway.
The MX records point to Intermedia and the email is being sent from various places, a Time Warner NYC, Verizon DSL, ATT's mobile pool of addresses among others. So trying to troubleshoot the originating IPs would be kind of a losing battle.
So the question is - does the A record being blacklisted matter or not? I assume it can't help, but is it likely the reason gmail is rejecting messages?
And furthermore, is it possible for the A record to get blacklisted for any other reason than it being the originating IP of spam? GoDaddy is trying to convince me that somehow the domain is blacklisted, not the web server, which makes no sense to me.
If I check the IP of the web server against mxtoolbox, it comes up blacklisted. If I check the domain it does as well - I assume because the web server address is the A record for the domain. It would follow from this that any other domains hosted on that web server, whose A records point to it, would have the same problem, correct?
can't verify as I don't have access to the web server to find another domain sitting on it to test with...
