You can do that in 'acl_smtp_connect', set a flag in an acl_c variable,
copy it to an acl_m variable.

or do it on HELO in acl_smtp_helo, or direclty into an acl_ variable per-
recipient in acl_smtp_rcpt [1]

acl_m variables survive into the queue with the message, and can be
tested in the routers until the final delivery has been made for that message.

The sort of test(s) that set said variable are up to you.

[1] with multiple recipients you will need to preserve each recipient's
data and concatenate each *successive* recipient's ID & data into a
structure built within the acl_m variable and extract it later, ELSE you
will preserve only the last one processed (or over-written in the DATA phase).
