SMTP and "From" address can be your actual email and SMTP server from your ISP if you plan to test and dev using the mail() function.
Myself, as i don't need to use the mail function offline I have this in php.ini:
Code:
[mail function]
; For Win32 only.
SMTP = localhost ; for Win32 only
; For Win32 only.
sendmail_from = me@localhost.com ; for Win32 only
But I could use my actual SMTP server from my ISP and my actual email (I may soon do it).
EDIT: php package like phphome are good, but you're better installing it yourself (IMHO).
