Are you talking on a ilegit web hosting issue (script under wordpress site) or 
a ilegit access to your webmail (squirrelmail)?
Or if I miss understood what are web hosting and webmail related?

Subject: [qmailtoaster] spamming on server

hi

i have a few websites along with qmailtoaster

i noted that one of the websites with wordpress was hacked and using a php 
script the spammer was injecting emails into the qmail queue ie there is 
nothing in the smtp logs, but the send logs contained 1000s of remote delivery 
entries.

i use squirrelmail but with smtp authentication only, ie email sent to external 
domains from my server has to smtp authenticate first.

my tcp.smtp is as follows

127.0.0.1:allow
:allow,BADMIMETYPE="",QMAILQUEUE="/var/qmail/bin/simscan",BADLOADERTYPE="M",CHKUSER_START="ALWAYS",
CHKUSER_RCPTLIMIT="50",CHKUSER_WRONGRCPTLIMIT="10",NOP0FCHECK="1",
DKQUEUE="/var/qmail/bin/qmail-queue.orig",DKVERIFY="DEGIJKfh",DKSIGN="/var/qmail/control/domainkeys/%/private"

how could the spammer directly inject email to the qmail queue ?

what am i missing here ?

thanks
rajesh
