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

This error normally happens when an exchange server talks to a mail server with greylisting.

I will send you a fix guide for exchange 2003 and below.2007 and later have fixed this issue.

Hi,

I'm suffering a rare problem when I receive e-mails from a exchange 2003 server to my qmail-ldap server.

Many mails sent from this server have this problem:
-----------------------------------------------------------------------
220 mx.mydomain ESMTP
EHLO exchange2003
250-mx.mydomain
250-PIPELINING
250-SIZE 26214400
250-DATAZ
250-STARTTLS
250 8BITMIME

MAIL FROM:<xxxxxxxx@exchange2003> SIZE=1433152
250 ok
RCPT TO:<me@mydomain>
250 ok
DATA
354 go ahead punk, make my day

// (1200seconds later...)

451 timeout (#4.4.2)


The exchange 2003 server can send without problem to other servers -as gmail.com or pobladores.com-.

It isn't a problem of mail size restriction or antispam policy. The delivery of a mail can fail X times and finally send ok. Others, expires after two days retrying.

Have you any idea?

Regards,
Spamis
