There's more than one way to do this. Alexander's approach is probably
the simplest, having multiple MTAs listening on different interfaces
(one on localhost, one on your external IP) and only scanning mail that
comes through the "external" MTA. However, this isn't a suitable
approach for you because in a different email you said that you use
fetchmail to collect mail and then push it through your local MTA (on
localhost presumably) to get the virus/spam scanning done. So you need
the milters to run on the localhost MTA. A slight variation would be to
run another, non-scanning MTA on a different localhost address (e.g.
127.1.1.1) and have your submit.cf use that MTA.
However, to answer your original question, I have my MSP send mail out
via my MSA, not my MTA, and this is how I do it:
1. Create an AUTH user ID for the client:
saslpasswd2 -a Sendmail -c -u <server-hostname> <msp-username>
--> when prompted, enter the password
2. Create an authinfo database for the client to use:
cat > /etc/mail/msp-authinfo
AuthInfo:127.0.0.1 "U:<msp-username>" "P:secret" "M:DIGEST-MD5"
^D
makemap hash msp-authinfo < msp-authinfo
chgrp smmsp msp-authinfo*
3. Add msp-authinfo.db to the end of the "all" target in
/etc/mail/Makefile
4. Add to submit.mc:
dnl Use the MSA with AUTH
define(`RELAY_MAILER_ARGS', `TCP $h 587')
FEATURE(`authinfo', `hash /etc/mail/msp-authinfo')
these need to go before the FEATURE(`msp'... line.
5. Add to sendmail.mc:
LOCAL_RULESETS
SLocal_trust_auth
R$* $: $&{auth_authen}
Rsmmsp $# OK
6. Update .cf files:
make
7. Restart sendmail
service sendmail restart
