Issue: unable to add new mailhosts. Spamcop Test fails - rcpt host rejects as probable spam

I've had 3 issues since attempting to move my email and host to NameCheap hosting.

Error report is below, I've tried with all three MX entries that Spamcop identifies, and have tried first and 3rd entry by themselves so that I can attempt to see if it was a "mass mail" attempt issue (eg all 3 at once) or to see if one would respond differently.

The message below is what I'm getting consistently now, where as the first attempts, I was getting a account / address invalid message, which I tested manually from Gmail successfully, and email has been flowing normally to my domain after relocation without issue.

I would like to note that my very very first attempt DID in fact get messages in and through to me, but when I attempted to validate them at Spamcop (eg .. click the link, then paste headers & message body) the processing on Spamcop's side said they couldn't see my message or headers, or similar .. (didn't capture it directly .. sorry)

Ever since that 1 first pass through that did send a message through all 3 but fail to validate .. I've been getting mostly the message below.

I've tried with my real email address and with the forwarder (*alias*) address that Spamcop knows me as, as well as a new one and still no luck.

Just FYI I've searched the forums, even tried looking for the instruction for reverting to the old method of mailhost entry and couldn't find that either.. 

obviously in the error below, the mailhost is *not* offline, a rejection was given --> "554 5.7.1 Rejected due to high probability of spam"

While I know the rejection is coming from my hosting provider (not a dedicated / solely my domain mail server) they are trying to work through this issue too.

This post is for visibility for anyone that searches, and hopefully once resolved a follow-up or resolved message can be posted.


Sorry, all tests failed.

We cannot deliver mail to the address you provided: XXXX_@_YYYYY.NET . Double check the address provided or try again later. Your mailhost appears to be offline.

Detailed errors:

Connecting to mx1-hosting.jellyfish.systems.:
smtpSend:smtpEnd: message transmission failed: 554 5.7.1 Rejected due to high probability of spam

Sometimes, mailservers are temporarilly unavailable. If you believe you have entered your email address and other details correctly, you might just wait a few minutes (or 24 hours) and try again.
