[exim] ACL testing

Hi,

I was kindly provided advice on an ACL to catch malformed messages that
cannot be scanned, I have input placed the below in the config:

check_mime:
     deny condition     = ${if eq
{$mime_content_type}{message/partial}{yes}{no}}
     message            = MIME error: MIME type message/partial not
allowed here

I am looking to test this as if I'm sending from a host authenticating
to the mailserver using it to send outbound.

You can test an acl in an exim config file by:

exim -C exim4.conf -bh 127.0.0.1

How would I test an individual acl such as the above please.

Kind regards
