A quick guide to locking down the SMTP Virtual Server in Exchange 2003

Stop Spam From the Inside by Locking Down SMTP

I was having this issue in one of the exchange servers i was working. Saw this huge amount of outgoing message queues.

Verified that the content was was only of bad emails outgoing, i then decided to wipe out all the pending email files (.eml) in "C:\Program Files\Exchsrvr\Mailroot\vsi 1\Queue". You need to stop the SMTP Virtual Server before you do this.
