[Matt Bednarik]

When i look through my maillog i find this:   ep 13 10:29:45 alpha sendmail[51522]: h8DFTjF6051522: localhost.prismequine.com [127.0.0.1] did not issue MAIL/EXPN/VRFY/ETRN during connecti on to MTA I am running squirrelmail 1.4.1 on apache 2.0.47 and php 4.3.2. Mail will send but i get this error. I also notice a lot of logging in and out during login like so:   Sep 13 10:29:02 alpha imapd[51505]: Login user=julie host=localhost.prismequine.com [127.0.0.1] Sep 13 10:29:02 alpha imapd[51505]: Logout user=julie host=localhost.prismequine.com [127.0.0.1] Sep 13 10:29:03 alpha imapd[51506]: Login user=julie host=localhost.prismequine.com [127.0.0.1] Sep 13 10:29:03 alpha imapd[51506]: Logout user=julie host=localhost.prismequine.com [127.0.0.1] Sep 13 10:29:04 alpha imapd[51507]: Login user=julie host=localhost.prismequine.com [127.0.0.1] Sep 13 10:29:04 alpha imapd[51507]: Logout user=julie host=localhost.prismequine.com [127.0.0.1] Sep 13 10:29:05 alpha imapd[51508]: Login user=julie host=localhost.prismequine.com [127.0.0.1] Sep 13 10:29:05 alpha imapd[51508]: Logout user=julie host=localhost.prismequine.com [127.0.0.1] Why so many logins? I have a small userbase, but in a large user base, wouldn't this bog down the server much more than normal?
