could not notify senders and postmaster

[Marc Mc Guinness]

Hello,

I've activated sending messages to the senders and to the
postmaster, but it doesn't work:

I'm using sendmail 8.12.6-6 on Debian 3.0.

My entries in mailscanner.conf are:
---------------------------------------------------------------------------
Deliver To Recipients = yes

Deliver From Local Domains = yes

Notify Senders = yes

//the following 3 files are in the path
Sender Virus Report =/etc/mailscanner/sender.virus.report.txt

Sender Bad Filename Report =
/etc/mailscanner/sender.filename.report.txt

Sender Error Report = /etc/mailscanner/sender.error.report.txt

Notify Local Postmaster = yes

Local Postmaster = postmaster
//also tried postmaster at mydomain.com -didn't work

MTA                = sendmail

Sendmail           = /usr/sbin/sendmail
//Tried calling /usr/sbin/sendmail from command line and it worked
---------------------------------------------------------------------------

The error message in /var/log/mail/mail.info says:

Can you please help me?
