logs and responses

[Oscar Arranz]

Hi all.

        I'm running qmail over Solaris for about 250 virtual domains, my
first
question is: �how could I write the log in a file of my election? (i.e.
/var/qmail/log/qmail_log )

        The second question is: When a message for [EMAIL PROTECTED]
arrives to my
system, and [EMAIL PROTECTED] is a non-existent user on my existent domain
domain.com, qmail puts it on [EMAIL PROTECTED] Maildir. �Someone can
tell me if there are any script developed for sending an error response
to sender?

Thanks in advance.
