It looks as if the problem is solved.  From my sendmail.mc:

INPUT_MAIL_FILTER(`greylist',`S=local:/var/run/milter-greylist/greylist.sock,\
F=, T=S:4m;R:4m')
define(`confMILTER_MACROS_CONNECT', `j, {if_addr}')
define(`confMILTER_MACROS_HELO', `{verify}, {cert_subject}')
define(`confMILTER_MACROS_ENVFROM', `i, {auth_authen}')
define(`confMILTER_MACROS_ENVRCPT', `{greylist}')

The "F=, T=S:4m;R:4m" sets the timeout.  I think this should be
included in the README.  This is documented in
http://www.sendmail.org/doc/sendmail-current/libmilter/docs/installation.html

I haven't had any error messages on my two machines since I did this
last night.
