My apologies for not reading the original message. I was merely mentioning
what the wildcard was in MySQL.

This will not work in the relay_domains setup. $key is what we are looking
for and if '$key=mail.domain.com' then '%$key' will not match 'domain.com'
from the database but SUBSTRING_INDEX('$key', '.',-2) will match
anything.domain.com.
if 'domain.com' is listed in the database:
if $key=mail.domain.com then
SELECT domain FROM domain WHERE domain LIKE '%$key'
this query would not match anything in the database at all, since
mail.domain.com is not in the database.
but
SELECT domain FROM domain WHERE domain LIKE SUBSTRING_INDEX('$key', '.',-2)
this query would take $key and make it eq domain.com then it would match and
allow relay.
Plus you can get some conditions where the % will not work such as the
relay_domains setup. This will allow you to just enter domain.com and this
would allow anything.domain.com to relay without entering every host name
you want to relay.
Later,
Brian
