But I thought exim just pipes the mail to dovecot-lda and then
dovecot-lda looks up the user info, home and mail location and
actually writes the file, exim doesnt do any database lookups or am I
totally in the dark?

OH! Well damn, look I have a router_home_directory, so... hm, do I
assume exim passes this to dovecot-lda somehow as an environment
variable or something?

I swear I looked at this like 50 times last night...

router_pop:
    debug_print= "R: dovecot_deliver for $local_part@$domain"
    driver = accept
    transport = dovecot_deliver
    local_parts = mysql; SELECT username FROM SQL_AUTH LEFT JOIN
(SQL_POP) ON (SQL_POP.user_id = SQL_AUTH.user_id) WHERE username =
'${quote_mysql:$local_part}' AND domain = (SELECT IF( STRCMP('',
'${quote_mysql:$domain}'), '${quote_mysql:$domain}', 'olypen.com') )
AND SQL_POP.status != 'disabled'
    router_home_directory = ${lookup mysql {SELECT SQL_POP.maildir
FROM SQL_AUTH LEFT JOIN (SQL_POP) ON (SQL_POP.user_id =
SQL_AUTH.user_id) WHERE username = '${quote_mysql:$local_part}' AND
domain = '${quote_mysql:$domain}' LIMIT 1}}
    user = 8
    group = 8
