I have a VPS running Windows 2008 server with plesk 9, which I am using for email. I asked to my ISP to add a PTR record, which they did but my mails still droping into spam box.
I have checked almost every DNS tool I can think of, and sometimes it shows the PTR record and sometime it does not. I'm not sure where the problem is.
This morning and all day intodns was showing i have a reverse ptr but right now not.
Could anyone point me to the right direction to find out where is the problem.
Thanks a lot.

81.222.137.195.in-addr.arpa -> no reverse (PTR) detected

Something is funky with your ISP's DNS.
There are two authoritative nameservers for
222.137.195.in-addr.arpa.
:These two servers are out of sync: NS1 has zone serial 1334308835 and is returning your PTR record. NS2 has zone serial 1330809486 (older), and is not returning your PTR record.
Anyone whose query is (randomly) sent to NS2 will not get your PTR record.
Instruct your ISP to fix this issue and all should be right in your DNS universe.
NS1
NS2
