smtp ta problem? (was: Re: hotmail problem... again :-( )

["Mariano Absatz" <zmailer@lists.com.ar>]

Hi Matti,

it happened again... though this time the smtp ta is being run with "-77", 
it is somehow bouncing a message with status "OK" (2.0.0) after being 
forcefully (and silently) disconnected from the smtp server.

As the transcripts were rather long, I uploaded them so you can browse 
them.

In http://www.baby.com.ar/ZMailer/hotmail-bounce.msg is the bounce message 
generated by zmailer.

I edited it a little to delete all the "RELAYED" data and concentrate on 
the "FAILED" part. The edited message is at 
http://www.baby.com.ar/ZMailer/hotmail-bounce-edited.msg

The smtp ta log corresponding to the specific smtp ta process is in 
http://www.baby.com.ar/ZMailer/smtpwebs.30529

The edited version (only showing the job involved) is at 
http://www.baby.com.ar/ZMailer/smtpwebs-edited.30529

Relevant parts of scheduler.conf follow:

*/*     interval=1m
        idlemax=4m # Max lifetime of idled TA before it is killed
        expiry=3d
        expiry2=2d
        retries="1 1 2 3 5 8 13 21 34"
        maxchannel=0
        maxring=20
        maxta=0 # Let it be automagically determined
        user=root
        group=daemon
        ageorder
        overfeed=150
        # nice=2
        ##priority=0
        # sysnice=-2
        # syspriority=-2

# smtp/*hotmail.com
smtp/hotmail.com
smtp/*.hotmail.com
        maxchannel=199
        maxring=33
        maxthr=8
        overfeed=20
        command="smtp -P -77 -s -l ${LOGDIR}/smtpwebs"

Do you have any idea about what is going on?

Thanx in advance.
