How to enable SMTP AUTH with FreeBSD default Sendmail 8.11

1) Add the following to  /etc/make.conf:

    # Add SMTP AUTH support to Sendmail
    SENDMAIL_CFLAGS+=	-I/usr/local/include/sasl -DSASL -D_FFR_UNSAFE_SASL
    SENDMAIL_LDFLAGS+=	-L/usr/local/lib
    SENDMAIL_LDADD+=	-lsasl

2) Rebuild FreeBSD (make buildworld, ...)

3) Create /usr/local/lib/sasl/Sendmail.conf with the following.

   pwcheck_method: pwcheck

4) Add the following to your sendmail.mc file:

   TRUST_AUTH_MECH(`DIGEST-MD5 CRAM-MD5')dnl
   define(`confAUTH_MECHANISMS',`DIGEST-MD5 CRAM-MD5')dnl
   define(`confDONT_BLAME_SENDMAIL',`GroupReadableSASLFile')dnl
   define(`confRUN_AS_USER',`root:mail')dnl

 ----

   Additional AUTH Mechanisms are LOGIN, PLAIN, GSSAPI, and KERBEROS_V4.
   These can be added to TRUST_AUTH_MECH and confAUTH_MECHANISMS as a space
   seperated list.  You may want to restrict LOGIN, and PLAIN authentication
   methods for use with STARTTLS, as the password is not encrypted when
   passed to sendmail.

   LOGIN is required for Outlook Express users.  "My server requires
   authentication" needs to be checked in the accounts properties to 
   use SASL Authentication.

   PLAIN is required for Netscape Communicator users.  By default Netscape
   Communicator will use SASL Authentication when sendmail is compiled with
   SASL.

   The DONT_BLAME_SENDMAIL option GroupReadableSASLFile is needed when you
   are using cyrus-imapd and sendmail on the same server that requires access
   to the sasldb database.
