AFAI understand this it seems that DrWeb specifies only those variables
which is necessarily used. Nothing more.
My installation (plain Sendmail with Milter-Greylist) has

O Milter.macros.connect=j, _, {daemon_name}, {if_name}, {if_addr}
O Milter.macros.helo={verify}, {tls_version}, {cipher}, {cipher_bits}, {cert_subject}, {cert_issuer}
O Milter.macros.envfrom=i, {auth_type}, {auth_authen}, {auth_ssf}, {auth_author}, {mail_mailer}, {mail_host}, {mail_addr}
O Milter.macros.envrcpt={rcpt_mailer}, {rcpt_host}, {rcpt_addr}, {greylist}, {client_resolve}


You may try this (in this manner that you merge them together!).

AFAIK additional variables needed for one milter should not harm the
operation of some other milter.

Looks like the minimum DrWeb needs ...

Milter-Greylist installation adds only these variables which are not
given in standard Sendmail environment. The required set is usually
greater.

The latter should be prefered.

I think, because some default variable coming from a plain/standard Sendmail
installation are still missing.

Is the .cf configuration file from the running system really the same as
the one you have generated from the .mc file?
What gives following?

/usr/lib/sendmail -bt -d64.100
