The mc Configuration Syntax
Under V8 sendmail’s mc configuration technique, you include delivery agent definitions in your configuration file using the MAILER( ) mc command. The form for that command looks like this:
MAILER(`name')
For example, SMTP and UUCP support can be included in your file by using the following two commands:
MAILER(`smtp') MAILER(`uucp')
If you include MAILER definitions for procmail
, or uucp
, those definitions must always
follow the definition for smtp
. Note, too, that any modification of
a MAILER definition (as, for example, with UUCP_MAILER_MAX)
must precede that MAILER definition:
define(`UUCP_MAILER_MAX', `1000000') ← here MAILER(`uucp') define(`UUCP_MAILER_MAX', `1000000') ← not here
The delivery agent M
definitions that correspond to MAILER( ) commands are kept
in the cf/mailer directory.
In general, the files in the cf/mailer
directory should never be modified. If one of the
definitions needs to be tuned, use the special keywords
described under the individual delivery agent equates (Delivery Agent Equates on page 736). For
example, the following line modifies the maximum message
size (the M=
delivery
agent equate, M= on page 746) for
the UUCP agent:
define(`UUCP_MAX_SIZE',`1000000')
Here, the maximum size of a UUCP message has been increased from the default of 100,000 bytes to a larger limit of 1,000,000 bytes.
