Spammers are very active now a days and they are constantly searching for vulnerable scripts or servers to send spam emails. One common vulnerability in servers is where mails can be send as nobody user. Nowadays most server administrators block this and mails are allowed to be send as a valid user created in the server. When we use the mail() function in php to send emails, the emails get send as the user nobody. So this won;t work in all servers. You won't get any error in the script. Recipients won't get the emails. The if(mail(***,***,***)) will return false in such cases.

One thing it can be difficult to control with this function is the envelope "from" address. The envelope "from" address is distinct from the address that appears in the "From:" header of the email. It is what sendmail uses in its "MAIL FROM/RCPT TO" exchange with the receiving mail server. It also typically shows up in the "Return-Path:" header, but this need not be the case. The whole reason it is called an "envelope" address is that appears _outside_ of the message header and body, in the raw SMTP exchange between mail servers.

Google is making a huge investment in developing the Ajax approach.
