Really? I found the downside of using signatures much worse than not
using them:

If the backend is mysql, eventually, we have to clean, and optimize the
signature tables... And the optimization locks the table. Needless to
say, all inbound mail can't be written to the signatures table.

Now, if you have a lot of users, your table optimization could take
hours to finish. Postgres has the same problem if you use a 'vacuum full'.

Cheers Johannes.

PS: your modified plugin worked like a charm for us. thanks a bunch!
