Although our eMail was working just fine, DNS Report said “it could not connect” which was true. That site had been temporary blocked as, for whatever reason, too many attempts were made using DNS Report to check our site. The Server thought it was an eMail Dictionary attack and temporaryly blocked the site from eMail access.
So there you go, other than sending pingbacks, everything is fine. 🙂
I hope this is the last time I have to talk about this here. I finally just set my mail server up to the same IP address, and let it sit there. I come back later today, and DynDNS tech support says it looks like things are basically fine. Checking with DNS Report, sure enough – my mail server is responding! I’m now a bit closer to ditching Gmail.
