What does the configuration file do?
The configuration file is responsible for telling sendmail
several important things about how it should handle mail:
- General configuration options, such as queue directory and timeout
values
- Definitions for each MDA, including pathnames and options
- Rulesets for header processing/rewriting, and the "routing table"
which determines which MDAs get used for which messages
This information can actually be quite complex, especially for a large
mail hub.
