Actually it's the other way around - sendmail-8.9.3 has {client_addr},
but not {if_addr}, while 8.10.0, 8.11.0 have both. So IMHO you don't
need configure flag (in case {client_addr} can be used instead of
{if_addr} of course).

BTW, I don't see X-Greylist header in received mails with 3.0, should I?

What about smfi_getsymval failed for {i}? Is it because Postfix does not
know the queue ID before it accepts the MAIL FROM command?
