3.12.1 Using mda with Sendmail.

When used with Sendmail, mda must be invoked from the local mailer definition in the file. The flags ‘lswS’ must be set for the mailer. These mean: the mailer is local, quote characters should be stripped off the address before invoking the mailer, the user must have a valid account on this machine and the userid should not be reset before calling the mailer. Additionally, the ‘fn’ flags may be specified to allow mda to generate the usual ‘From ’ envelope instead of the one supplied by sendmail.

If you wish to use mda with non-local authentication, such as SQL or LDAP, you also need to remove the ‘w’ flag, since in that case the user is not required to have a valid account on the machine that runs sendmail.

Here is an example of mailer definition in

Mlocal, P=/usr/local/sbin/mda,
        S=EnvFromL/HdrFromL, R=EnvToL/HdrToL,
        A=mail $u

To define local mailer in ‘mc’ source file, it will suffice to set:

define(`LOCAL_MAILER_PATH', `/usr/local/sbin/mda')
define(`LOCAL_MAILER_ARGS', `mail $u')
