Hello,
I am having a weird problem with PHP mail(). First of all it does not seem to be able to send mail (i.e the webmaster) to anybody - not even to registered users. Secondly, when I try to register as a new user I get the notification in my email to activate my account. If somebody else tries from another computer to register that person does not receive an email. Why is that? Why only from my pc someone can register and get email and from another pc it won't work?

Is your website can be accessed publicly ? Or it's only within your network (LAN)?
