I can confirm that your hint helps making the shortened example work, so thanks
for it.

BUT unfortunately I have two issues:

1) I don't understand your above comments. It's been many years ago when I was
fluent in "Eximish." Can you please be a bit more elaborate?
2) Your above advice doesn't help in the original code fragment, which is the
following:

-  headers_remove = ${if or {{<{$spam_score_int}{${lookup mysql{select
users.sa_tag * 10 from users,domains \
-                              where localpart = '${quote_mysql:$local_part}' \
-                              and domain = '${quote_mysql:$domain}' \
-                              and users.on_spamassassin = 1 \
-                              and
users.domain_id=domains.domain_id}{$value}}}} \
-                            { eq {0}{${lookup mysql{select
users.on_spamassassin from users,domains \
-                              where localpart = '${quote_mysql:$local_part}' \
-                              and domain = '${quote_mysql:$domain}' \
-                              and
users.domain_id=domains.domain_id}{$value}}}} \
-                          } {X-Spam-Score:X-Spam-Report:X-New-Subject} }

Thanks!
