I’ve got a server with a shared IP and 4 virtual servers using private IP’s. Two of the private IP’s are receiving mail fine, but the other two are not and after a few days kick back the error message:
Message will be retried for 1 more day(s)
Technical details of temporary failure:
The recipient server did not accept our requests to connect.
I can not figure out the difference between the ones working vs not working. Any advise would be appreciated.
I notice the other two that were working were in there of course, but they had their SSL cert info appended to the line. So must be I did something slightly different when I added the cert to those.
To make things more of a mystery, the broken ones show receiving email up to a few days ago and then stopped. Don’t know how the master.cf dropped them.
