I don't think there is a size limit - it is just a normal dbm file.
There are some sendmail configuration options that must
be set to activate it, and it might be particular about
ownership/permissions on the file:
http://www.sendmail.org/~ca/email/chk-89f.html#ACCESS_DB
There are some recent additions to functionality in the
access file with tagged entries:
http://www.sendmail.org/~ca/email/chk-810.html#810TagLHS
but if the tag is omitted it works as before.
