Lancer,
There is an NG FP2 Security Server hotfix. I can't quite remember now, but
I think we had similar issues until applying that. You may need to source
the hotfix from your reseller. Alternatively I'd image the fix is included
as part of FP3.

Subject: [FW-1] smtp 550 mailbox unavailable
Every so often the firewall sends a 550 Mailbox unavailable response on
inbound mail and logs it as content security - access denied. If the user
resends it will work. This started after we upgraded from 4.1 SP5.
Using a Sniffer I found this occurs when the firewall waits about a minute
after the connection is opened before sending it's 220 message. If firewall
responds quickly the process succeeds.
remote server: syn
firewall: syn-ack
remote server: ack
~60sec delay
firewall: 220 cp fw-1...
remote server: ehlo
firewall: 250 hello
remote server: mail from
firewall: 250 ok
remote server: rcpt to
firewall: 550 mailbox unavailable
