When not using any of the optional dbm tables, sendmail+IDA delivers mail via
|
|
the DEFAULT_MAILER (and possibly RELAY_HOST and
|
|
RELAY_MAILER) defined in the sendmail.m4 file used to
|
|
generate sendmail.cf. It is easily possible to override this behavior
|
|
through entries in the domaintable or uucpxtable.

|
A generic site that is on Internet and speaks Domain Name Service, or one
|
|
that is UUCP-only and forwards all mail via UUCP through a smart
|
|
RELAY_HOST, probably does not need any specific table entries at
|
|
all.
|
|
<P>
|
|
Virtually all systems should set the DEFAULT_HOST and
|
|
PSEUDONYMS macros, which define the canonical site name and aliases
|
|
it is known by, and DEFAULT_MAILER. If all you have is a relay
|
|
host and relay mailer, you don't need to set these defaults since it works
|
|
automagically.
|
|
<P>
|
|
UUCP hosts will probably also need to set UUCPNAME to their
|
|
official UUCP name. They will also probably set RELAY_MAILER, and
|
|
RELAY_HOST which enable smart-host routing through a mail relay.
|
|
The mail transport to be used is defined in RELAY_MAILER and
|
|
should usually be UUCP-A for UUCP sites.
|
|
<P>
|
|
If your site is SMTP-only and talks `Domain Name Service', you would change
|
|
the DEFAULT_MAILER to TCP-A and probably delete the
|
|
RELAY_MAILER and RELAY_HOST lines.
