Subject: [masterweb] Error pd Pendaftaran Forum - PHPBB





Saya baru install PHPBB3. Pada waktu saya coba untuk register (sebagai
anggota baru pd forum tsb), ada error: sendmail: Can't send mail: Sender
domain (gmail.com) does not belong to user, please use your own domain
sendmail: Can't send mail: Sender domain (gmail.com) does not belong to
user, please use your own domain X-Powered-By: PHP/4.4.4-8+ etch4+spbutters1
Content-type: text/html; charset=UTF- 8 Cache-Control: private,
no-cache="set- cookie" Expires: 0 Pragma: no-cache.

Apakah itu yg menyebabkan admin ga dapat email dari pendaftar? Ada yang tau
solusinya?
Terima kasih
