ok i did the squirrel mail instal using the ispconfig update thingy.
i can access squirrelmail by going to tools and going down to squirrelmail. There is a problem though. After i log into squirrel mail using my email address and password I goto options.personal info and i can change what email address it looks like i am sending from. I just sent myself an email from firstname.lastname@example.org
and I couldnt tell what my real email was.
Obviously i cant leave it like this for my customers.
how do i lock that down so they cant change what emial it looks like it is coming from?
