Michael asks about this recipe:
:0
* ^From(_dot_)*johndoe(_at_)somewhere(_dot_)edu
{
EXITCODE=69
HOST=done
}
Is the value for HOST simply a bogus hostname? What in this
recipe actually causes the mail to bounce,
The exit value. When sendmail gets a return value of 69, the mail
bounces.
Thanks for the help. This recipe worked, I'm just curious *WHY*.
There is not much of a trick. Setting host makes it stop evaluating
this file. setting the EXITCODE makes it return a certain value... It
is up to whatever is calling procmail to interpret the return value
