0) patching cf/m4/proto.m4 changes files used during generating
sendmail.cf (sendmail configuration file) - no recompilation of
sendmail binaries is required if your sendmail is already compiled
with socketmap support

Use the command below to find out if your sendmail supports sockemap:
/usr/sbin/sendmail -d0.1 -bv root | grep SOCKETMAP

1) There is RTCyrus3 (next version)
http://open-sendmail.sourceforge.net/rtcyrus3/

It has been designed for better support of cyrus virtual domain and
aliases
