Re: Strange problem with mail sent from Exchange 2003 server

Thanks, but I don't have greylist active... (but please, send me these  
fix guide when you can).

My qmail-smtp.rules (which generate qmail-smtp.cdb) for this exchange  
server is:

"xx.xx.xx.xx:allow"

My run script for qmail-smtpd is:

---------------------------------------------------------------
#!/bin/sh
exec 2>&1 \
envdir ./env \
sh -c '
     case "$REMOTENAME" in h) H=;; p) H=p;; *) H=H;; esac
     case "$REMOTEINFO" in r) R=;; [0-9]*) R="t$REMOTEINFO";; *) R=R;; esac
     exec \
     envuidgid qmaild \
     softlimit ${DATALIMIT+"-d$DATALIMIT"} \
     /usr/local/bin/tcpserver \
         -vDU"$H$R" \
         ${LOCALNAME+"-l$LOCALNAME"} \
         ${BACKLOG+"-b$BACKLOG"} \
         ${CONCURRENCY+"-c$CONCURRENCY"} \
         -x/var/qmail/control/qmail-smtpd.cdb \
         -- "${IP-0}" "${PORT-25}" \
     /var/qmail/bin/qmail-smtpd
-------------------------------------------------------------------

I'm analyzing tcp traffic with wireshark, I hope found something...

Regards
