Is it Possible To Disable All Emailng Done By Elgg?

Hey everyone,

I've been getting hit with an unbelievable amount of spam signups and things like the number of confirmation emails etc is causing issues with my host because they think I'm mass mailing.

Is there a way to disable all types of mailing done by elgg?

From what I understand (but I'm a noob so correct me if I'm wrong) the mail i sent out from the engine/handlers folder? Can I just delete one of the files in there to remove all mailing or edit one of them or something?

Any help is greatly appreciated :)
