Where are the "from" email addresses in the database stored?

Hi all,

Hopefully someone will be able to answer this in a heartbeat, I've looked but cannot find them... Somehow or other, I seem to be in a position where I have 3 differing email "from" addresses that fire out alerts / resets. Looking through my Advanced Alert manager for all activated alerts, I don't see them. So.. if someone knows what table etc these are kept in in the DB, please let me know as I'd like them to be uniform & also to try & track down what I believe to be duplication of emails being sent out...

Hope this is clear? If more elaboration is needed, please let me know..

Thanks all,
Daniel
