Can you please provide more info on Mail(2)? In the FAQ, it only states:
Mail (2) is yet another mail section, except that this is an optional section. Mail (2) works in completely the same manner as Mail. To activate Mail (2), check the Use mail (2) box.
However, this doesn't specify what exactly Mail(2) is. From a google search I have deduced it to being some sort of autoresponder. But is there a tutorial somewhere that teaches me how to set it up exactly?
