Are there no cases where cyrus itselfs submits messages using directly /usr/lib/sendmail ? I would like to avoid the warning header "sendmail used the -f flag to send the from address". How does then Cyrus send it's auto-generataed failure messages like when there are no mailbox at address [EMAIL PROTECTED] ? Regards Marc
