SMTP Transaction TIme not Good, Exchange 2007 Sp2 on Windows 2003 with Barracuda Spam filter
Posted on 2015-01-08
we are experiencing email bounce backs from certain domains when they try to email us. Running mxtolbox diags shows a transaction time of 18.23 seconds. The setup is Barracuda spam filter which forwards to hub transport server, which goes to exchange mailbox. Running exchange 2007 sp2. Saw a few error thrown up on the transport server :
1. The background scan of the transport queue database has completed. 259 message(s) were found.
Have checked the queue and they are empty. Don't know where this counter is coming from.
2. Also get msexchang common performance counter update error message.
Highly appreciate if any one could guide where to start looking for .
