Reverse DNS does not match SMTP Banner

Hello everyone,

After 02 months, my ISP finally helped me with Reverse DNS / PTR records. Now when I test my email server on MXToolBox, it states the following error on MXToolBox:

1- Reverse DNS does not match SMTP Banner

My email client is also not able to login to the IMAP. Previously, the email client could login to both IMAP/SMTP and only email was being rejected due to no PTR record.

I believe the tech guys at ISP didn't enter it correctly. The domain is caretakers.pk

Any help would be highly appreciated!

Thanks and regards,
