Hi! I've been managing to install ISPConfig2 for about a week and I've finally managed to install it with everything working. I've also added the DNS records and everything. The problem I'm having now is with Mails. I've installed squirrelmail package with ISPConfig 2 which I downloaded from the ISPConfig page. I've created a mail on ISPConfig named firstname.lastname@example.org I'm not being able to send mails to my domain email@example.com from the outer world, I haven't been able to test from the inside. But when I log onto my mail through SquirrelMail and send me a mail to the outside world I receive the mail like this: firstname.lastname@example.org And when i reply i get this Code: Delivery to the following recipient failed permanently: email@example.com Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 #5.1.0 Address rejected firstname.lastname@example.org (state 14). ----- Original message ----- Received: by 10.213.99.207 with SMTP id v15mr1101842ebn.108.1310251234184; Sat, 09 Jul 2011 15:40:34 -0700 (PDT) MIME-Version: 1.0 Received: by 10.213.27.65 with HTTP; Sat, 9 Jul 2011 15:40:14 -0700 (PDT) From: Cristian Eduardo Lehuede Lyon <email@example.com> Date: Sat, 9 Jul 2011 18:40:14 -0400 Message-ID: <CABcpnkxoHn3WGm6fs3+4n=+fca_Xbw3Vd0oYxCH5EqOka=O48w@mail.gmail.com> Subject: sdasddassda To: soporte <firstname.lastname@example.org> Content-Type: multipart/alternative; boundary=00504502d374614c0b04a7aaa3ff dassadsaddsaasdadssda Any SUggestion?
