Spam: Re: # SENDMAIL_RELAY Question

[Pentland G.]

This is M4...  when you do the make it will add this (slightly altered) into the cf.  You shouldn't ever modify the cf file by hand.

What this will do is force the box with this code to send all mail that *would* be selected as local (and use the local delivery agent) the to host you specify.

It also does some address rewriting.

If you're not familiar with this kind of stuff then I suggest you read the o'reilly book on sendmail.

Before you make this live ensure you have thoroughly tested it and it does do what you expect and want.

Sendmail -bt (and optionally some other flags) puts sendmail into test mode.

/parse user at domain.com

will run that address through the rules and it'll tell you what it will do.

Hope that helps.

Sorry i´m not very familiar with sendmail config. Where should i add 
this (sendmail.m4 or sendmail.cf)

When i add this, will the machine called mailscanner relay the mails or 
must i add all domains to /etc/mail/relay-domains ?
