hi experts,

i have a hardware load balancer load balancing a pair of exchange 2010 servers.  The load balancer has a Virtual IP address and each of the exchange 2010 server has their own individual public IP address.  each exchange 2010 server has CAS, HUB and Mailbox roles configured.l

mail will be sent to the virtual IP address and will be distributed to one of the exchange servers, and when replied, it will be replied back from one of the exchange servers and the sender will see the exchange server public IP address instead of the virtual IP address.

will stricter spam filtering appliance block my exchange server mails / filter my exchange server mails because they are from different IP addresses?

is it necessary for email sent to a virtual IP (load balancer virtual IP)  be replied with the same virtual IP (NAT'd)?

Thanks!

Nope, spam rules may check existence of PTR, SMTP responses or whatever but not do a MX search on your DNS and compares with received email because lot of domains not uses same IP from send and to receive emails.
