[exim] "acl_not_smtp" ratelimit

Hi,

I want to ratelimit on a per recipient basis but in the "acl_not_smtp"
acl rather than the "acl_smtp_rcpt" acl.

The documentation at
http://www.exim.org/exim-html-current/doc/html/spec_html/ch40.html#ratoptmea
suggests to me that you can only ratelimit on a per_rcpt basis in
acl_smtp_rcpt. Is that correct?

Mike
