I assume you are running spamassassin at SMTP time (using the spam
=... ACLs)? This looks like the wrong thing to do in your use case
since you *never* want to reject mail at SMTP time because this would
only upset fetchmail.

Running spamassassin when delivering or as a transport filter should
work better, in that case fetchmail does not need to wait (timeout)
for spamassassin to run.

The bounce is always sent to the (envelope sender).

The idea is to
a) edit /etc/exim4/exim4.conf.localmacros
for stuff whith predifined hooks, e.g. to override trusted_users =
uucp by defing MAIN_TRUSTED_USERS.

b) directly edit the dpkg-conffile /etc/exim4/exim4.conf.template (or
the split up version) otherwise.

Of course there is a point where it is better and simpler to ignore
the Debian configuration and simply manually build a
/etc/exim4/exim4.conf.
