Did you think yourself about the problem before you asked here? The statement is pretty easy to do, just translate english to SQL:

Update my mailbox table and set active to 0 where expiry is less than now:

UPDATE mailbox SET active = 0 WHERE expiry < NOW()

Notice: It would be better to check expiry < NOW() every time you select something from the table because an entry could expire and be queried before the next run of your expiry-statement.

An even cleaner approach might be to use a view containing the necessary constraints (filtering for "active" and "expiry"). – the-wabbit Jan 24 '13 at 10:11
