Hi,

I've an SBS server and a mac email server. My DNS is hosted on the mac, and
on the SBS it's a secondary. On my dns settings I have 2 MX records

domain.com MX 10 dns2.domain.com
domain.com MX 20 dns.domain.com

dns2.domain.com IN A sbs's public ip address
dns.domain.com IN A mac server's public ip address

When I send emails from external, on my external mail server's log it showed
that emails are sent to sbs's ip but inside my exchange I can't seem to see
any emails at all.

So to test whether was it my DNS settings which is having problems, I
stopped the exchange services in sbs and mails start to flow into the mac
email server without any problems. So now I suspect its my exchange which is
having problems but what problem exactly? Can anyone help me please? Thanks
in advance
