Re: [Dovecot] Dovecot SQL user_query
yes, something akin to this (assuming they are in the same schema) .
sorry i cannot be more helpful with the query. the secret is the
chance to retrieve multiple results, but limiting those results to one
row and having them priroritized mail > users
user_query = select mail from (select mail from table where email = ?
union select home as mail from users where email = ?) limit 1

This might help http://dev.mysql.com/doc/refman/5.1/en/if-statement.html if you must go down this terrible rocky bumpy country road (yep, I know some managers just are too scared of change, but most are open to discussion). > Please don't question me about this setup. I inherited this mess from > the previous Network Admin. Alex, maintaining a broken system, is not optimum, why not just fix it so it's all in one? Most employers want reliability and stability, if they are the obstacle, explain to them the nightmare it is now and how easy it is to uniform everything, if you do it right, they'll likely remember that when it comes to future contract/salary/wage negotiations.

You probably want to do an "if condition" or similar type query. It has
been ages since I played with MySQL. You might want to read up on the
query syntax.
