Kenny, I think the time problem is related to the virtual server software I'm using. But the head node has 2 dual core intel's with 8 gig's of ram with 7,000 users. The cpu stays at about 60% idle. I will be moving away from the virtual server stuff and into a stand alone server hopefully this helps out the situation.

We found at our site to keep Apache/squirrelmail happy, we dedicated a server for our webmail users. Mostly being a RAM issue in that case.

It'll affect it in that you will be having 1 sec delays frequently it seems. You should definitely look into fixing that. That is bad behavior for a busy mail server. -- Kenny Dail <[EMAIL PROTECTED]>
