Can anyone shed light on this?
Couldn’t access smtp via wp, spoke with d9 hosting several times and eventually they whitelisted mxroute ip address in their firewall. Everything worked fine for almost a day.
Yesterday (I’d setup an ar series to keep and eye on the smtp) nor emails were sent, checked in wp and ports 25, 465 and 587 are blocked.
Response from d9…
I have checked the message in the live chat and found that the IP of the remote mail server is already white listed. Since it is permanantly added to the firewall it is not blocked from our end. We are also able to telnet to 25, 465 and 587 from our end. If you are not able to connect with them, please check with the remoe email service provider.
If you have any further questions please do not hesitate to get in touch with us.
Any help really appreciated
