Hi, Karsten -
I can't spot anyone replying to this so, belatedly…
You might be looking at the wrong thing. In your message you seem yo say
that your Exim configuration includes this:
acl_check_data:
condition = ${if < {$message_size}{1M}}
If so then the error is accurate and is telling you that you've forgotten
to start the statement with a verb. That is, you need something like an
*accept*, *deny* or *warn* before your conditions (such as *condition*).
The verb tells Exim what action to take when all the conditions in the ACL
statement are met.
Cheers,
Mike B-)
