Please keep me CCd.
exim v4.64

I have the following router on one of my mail servers:
auto_whitelist:
        driver = redirect
        domains = !+local_domains
        sender_domains = +local_domains
        condition = no${lookup mysql{SELECT 'no' \
                                        FROM lists.auto_whitelist \
                                        WHERE sender='$sender_address_local_part' AND \
                                                recipient='${quote_mysql:$local_part}@$domain' \
                                        LIMIT 1 \
                                  } \
                             {} \
                             {${lookup mysql{REPLACE INTO lists.auto_whitelist \
                                                (sender, recipient) \
                                                VALUES ('$sender_address_local_part', \
                                                        '${quote_mysql:$local_part}@$domain') \
                                            } \
                                            {} \
                                            {} \
                               } \
                             } \
                     }
        data = :blackhole:
        unseen
        no_verify
        no_expn
        no_address_test


The only reason for this is to add data to a database at routing time.
condition is always "no" so it should never work, unfortunately, it runs only
if the SELECT statement returns any data. What's even worse is that unseen
is not honoured.

The entire ${lookup is not supposed to return anything.

If I comment out the lookup part, it works as expected.

If I comment out the inner ${lookup (the one that does the REPLACE INTO), it
also works as expected.

If I change :blackhole: to :defer:, it works as expected.

Any one have any ideas on this?

Here's the exim -d+expand on sending an email. Only the auto_whitelist
router is listed (note, the email address has been modified from wakko@ to
wakko#)
