When in doubt, read the release notes file.
[Incompat 20090428] The default milter_protocol setting is increased
from 2 to 6; this enables all available features up to and including
Sendmail 8.14.0. The new milter_protocol setting may break
compatibility with older Milter libraries or applications, and may
cause Postfix to log warning messages such as:
warning: milter inet:host:port: can't read packet header: Unknown error : 0
warning: milter inet:host:port: can't read packet header: Success
warning: milter inet:host:port: can't read SMFIC_DATA reply
packet header: No such file or directory
To restore compatibility, specify "milter_protocol = 2" in main.cf.
