This could be your reason why.

FAIL    Reverse DNS entries for MX records      ERROR: The IP of one or
more of your mail server(s) have no reverse DNS (PTR) entries (if you
see "Timeout" below, it may mean that your DNS servers did not respond
fast enough). RFC1912 <>  2.1
says you should have a reverse DNS for all your mail servers. It is
strongly urged that you have them, as many mailservers will not accept
mail from mailservers with no reverse DNS entry. You can double-check
using the 'Reverse DNS Lookup' tool at the DNSstuff
<>  site (it contacts your servers in real time;
the reverse DNS lookups in the DNS report use our local caching DNS
server). The problem MX records are: [No reverse DNS entry (rcode: 3 ancount: 0)
(check it <> )]

Since about 9:00 AM yesterday, we are not able to forward mail to
through our SMTP Virtual Server.
Anybody else having this problem.
