It's quite likely you never configured a mail subsystem on your Debian box. PHP on Linux needs a sendmail-style interface to send out mails. In most cases like this, you wouldn't need a large system like Exim or Postfix but instead a simple relay-only server like Nullmailer or SSMTP would suffice.

My server is in 1and1, i am using another package and there is no problem about pligg. I bought a new package and the problem on the new package not old one. –  Barkat Ullah Jan 2 '13 at 13:24
    
If this is a shared hosting package, you need to contact 1&1 support. –  Sven Jan 2 '13 at 13:28
