Thanks for the reply, sorry Ive been out and been unable to reply until this morning.
12 concurrent connections
2 procs - VMWare
No load balancing, no clustering
Im not 100% sure on the logs, from the requestprocessor log:
NFO: RPT(2e) Waiting for new connection

java.lang.NullPointerException

For whatever reason, the smtpprevent log is not showing the connection as closing now?
From a wireshark capture, I see the ACKS from Exchange to DLP, and DLP to Ironmail, and then SMTP Proxy Server Ready, then the EHLO command, which leads to:
421 4.3.0 Fatal Processing Error. Closing Connection.
Im at a loss. The server is running on VMWare 5, so Im wondering if this is somehow the issue. Could lowering the concurrent queue possibly help? We're not really sending a lot of mail, so perf shouldnt be an issue.
Thanks again for the reply!!
