I have a customer that's complaining of erratic performance delivering
email to us. Sometimes it comes through; other times, it doesn't.
I'm admittedly over my head, but I suspect a spam related blocking due
to a PTR record mismatch. They are sending mail from three domains,
nbf-trio.com, trioads.com and trionw.com. They all share the same email server
at 64.62.8.154. The PTR record reads mail.nbf-trio.com. The server's same in
an SMTP session is trionw.com.
We're running Exchange 2007 SP1.
Exchange anti-spam is enabled, but all three of their domains are on
our allow list.
We're also running Forefront, but all blocked emails are quarantined
and we're getting nothing there.
I obviously have little contraol over a customer's email system. How
can I ensure that we recieve their emails?
Thanks in advance,
Steve
