we're doing a string expansion, which will request a lookup...

08:33:42 4098 |--expanding: $host
08:33:42 4098 \_____result: easthope.ca
the key we're looking up is the destination host for the transport, "easthope.ca"

this is the DB we're to do the the lookup in

... sounds like that's the right answer, given the file content.

Correct. Before that close from it, we see:
08:33:43 4098 sync_responses expect rcpt
08:33:43 4098 SMTP<< 550 SMTP AUTH is required for message submission on port 587
meaning: we wanted it's response to a "RCPT" comamnd we sent it,
and that response was and error code (the 550 value) along with
a comment for humans "SMTP AUTH is required for message submission on port 587".
So we didn't manage to authenticated ourselves to them. In fact, we
didn't event try, probably because that lookup didn't find a match for that
key.
