Re: sendmail not working for relaying messages

Hello,

I am trying to setup Outlook Express (email client to setup mail accounts) , when I try to send mails outside my domain like @mydomain.com ie to yahoo or gmail or hotmail, I get this error message

"The message could not be sent because one of the recipients was> rejected by the server. The rejected e-mail address was 'janu@xxxxxxxxxx'. Subject 'test', Account:'mail.relate24seven.com< http://mail.relate24seven.com>> ',> Server: '65.103.191.30 < http://65.103.191.30>', Protocol: SMTP, Server> Response: '550 5.7.1> <janu@xxxxxxxxxx>... Relaying denied', Port: 25, Secure(SSL): No,> Server Error: 550, Error Number: 0x800CCC79.

I can send mails to @relate24seven.com in OE .If this is an OE problem , then I have the same problem with Thunderbird mail client too ; while sending emails it prompts fro password I type in the same password as used for incoming mail server which is the same as the outgoing one , and it does not work

When I try to do nmap localhost it shows this :

PORT      STATE SERVICE
21/tcp    open  ftp
22/tcp    open  ssh
25/tcp    open  smtp
80/tcp    open  http
110/tcp   open  pop3
111/tcp   open  rpcbind
113/tcp   open  auth
143/tcp   open  imap
443/tcp   open  https
631/tcp   open  ipp
3306/tcp  open  mysql
5900/tcp  open  vnc
10000/tcp open  snet-sensor-mgmt

But when I try nmap 65.103.191.30, it shows this :
(The 1658 ports scanned but not shown below are in state: closed)
PORT   STATE SERVICE
23/tcp open  telnet
80/tcp open  http

Any help with this?
