Some people have already told me that this problem was discussed on this
mailing list long before but I couldn't find that message. I have this
router:
mysql_user:
driver = accept
condition = \
${if eq{} \
{ ${lookup mysql {SELECT maildir FROM users \
WHERE id='${local_part}@${domain}'}} \
} \
{no}{yes} \
}
# retry_use_local_part
transport=mysql_delivery
the problem is that exim thinks that condition is true even if mysql
returns empty string (that actually means user doesn't exist). How
should I change the condition in order exim treats mysql answer properly?
