Changing sendmail binary from original sendmail to Exim sendmail solved the problem.

Just one question, if is there someone who use courier with dovecot deliver ?

How should i set up DEFAULTDELIVERY in courierd config file ? When i try setup via dot-courier file in 
users home directory then file looks like this

| /usr/bin/spamc -U /var/run/spamassassin/spamd.sock -e /usr/libexec/dovecot/deliver -f $SENDER

but i can't use $SENDER in courierd config file, or i don't know how, and without this option vacation 
plugin  does not send reply.

Thank you

Martin
