PTR Record in Exchange

Hello,

Lately, some ISPs have deemed our regular emails as SPAM even though they are just regular emails.  I have read that this may have something to do with the PTR record.   Our mail server address was assigned by the ISP and our internal network is on its own subnet with different IP addresses.  How can I determine if a PTR record was created on my end or the ISP end?  How can I create a PTR record if need be?

Thanks

Lookup your MX record (use iptools.com, DNS Lookup, type in your domain name and select MX), it's usually something like MX 5 mail.yourdomain.com, look at the corresponding A record for mail.yourdomain.com, then do a reverse lookup on that IP (use iptools.com or dnsstuff.com), if it doesn't come back with x.x.x.x is mail.yourdomain.com, then you will need to contact your ISP and ask then to add a reverse PTR record for that IP.
