Hello fellas,
we are getting this alert on dnsstuff and some clients are having email (send) problems.

WARNING: The hostname in the SMTP greeting does not match the reverse DNS (PTR) record for your mail server.

how can i check of fix this?

Tip:
i have other VPS with Plesk (same version) and this "SMTP greeting" are working fine.

Ask your data center company to create a PTR record to match your Plesk server hostname. Example, my Plesk server is webserver4.domain.com and I submitted a request to my data center to make a PTR record for the IP of my server to match. Now depending on the company/VPS provider you are using this can even be done by you. Also they might need you to create records within your zone before they will complete your request. Also note after they make the update I have seen it take u pto 48 hours for PTR records to process thru.

Alternatively you can make the hostname of your server to be the same as the current PTR.

Also another good idea as long as there PTR isn't something that "looks" like a dynamic assigned IP address. Just spent a week fixing my delivery to aol.com because they didn't like one of my PTR records showing as webserver4-1-1-1-1.domain.com (all the 1-1-1-1 part was the IP of that server) so I had to change them all.
