BTW, if you're using a new version of sendmail then the authentication
instructions in the sxs won't work.  Sendmail now runs as non-root and has
changed a few things.

authinfo (I'm going from memory here) no longer works.  It been replaced
by a tag with similar data in the access database.  The access directive
has new parameters.  Also, sendmail can't access the /etc/sasldb file
since only root has permission to do that.  Changing the permission causes
complaints that the file has wrong permissions.  You can work around this
by including a DontBlameSendmail directive in sendmail.mc.
