[exim] ACL variable for SMTP error

Hello

I'm trying to capture a certain SMTP error code upon sending mail. However
i'm no such luck to where this is stored during transaction.

For example

Trying to capture the "550 action not taken" from the below.

SMTP error from remote mail server after end of data: host
ASPMX.L.GOOGLE.COM [173.194.76.26]: 550 Action not taken


Many thanks
