https://bugs.exim.org/show_bug.cgi?id=3066

--- Comment #8 from David Saez <david@???> ---
I found that the only way to reproduce it is to have the password hardcoded oin
the lookup:

warn    condition       = ${lookup mysql{servers=server/database/user/password;
INSERT INTO abuseols.emails \
                                (mid,fecha,ip,email) VALUES ( \
                               
'${quote_mysql:$message_exim_id-$pid@$primary_hostname}', \
                                NOW(), \
                                '${quote_mysql:$sender_host_address}', \
                                '${sender_address}')} \
                            {yes}{no}}
