They are, +1. the name of the file which holds the contents of the email to be sent. +2. The name of the file which holds the SMTP headers of the email. + +The SMTP headers are passed in the exact same way as they are passed to the +user's Mail Transport Agent (MTA). In effect, the email given to the user's +MTA, is the contents of $2 followed by the contents of $1. + +An example of a few common headers is shown below.

This counter does not follow the + patch series counter scheme.

Some placeholders are left for +additional validation steps to be performed after all patches of a given series +have been applied. fsmonitor-watchman ~~~~~~~~~~~~~~~~~~ |
