I can't resolve problem with ISP and PPP

[Sinisa Malesevic]

I cant resolve my problem then I must  try to describe my configuration. We have a LAN with 9 workstation (all windows 95/98/NT) and  on one PC is DNS with Windows NT 4.0 . Our ISP is eunet.yu (mail servers are relay.eunet.yu (SMTP) and solair.eunet.yu (POP)) and we connect with dial up. Our local domen is named infor.co.yu. On my PC (named oper) is RED HAT 6.0. and is connected on isp with dial up. We would like to use my PC like mail server and we would like all workstation send mails over my PC. We have viritual domens infor.co.yu and motor.com and users have mail address like: [EMAIL PROTECTED] POP server is started like: tcpserver 0 110 /var/qmail/bin/qmail-popup oper.infor.co.yu \ /home/vpopmail/bin/vchkpw /var/qmail/bin/qmail-pop3d Maildir & SMTP server is started like: tcpserver -x/etc/smtp.smtp.cdb -u502 -g501 0 smtp /var/qmail/bin/smtp-smtpd & I make a maildir for outgoing mail in the "alias" home directory (/var/qmail/alias) like: #maildirmake ~alias/pppdir I put ./pppdir/ into ~alias/.qmail-ppp-default and :alias-ppp into /var/qmai/control/viritualdomains For masquerade my local name with name of ISP I added "[EMAIL PROTECTED]:alias-eunet.yu" On file ./qmail-eunet.yu-myispusername (/var/qmail/alias) I added one line "&[EMAIL PROTECTED]" I when I established PPP conection with my ISP (I determine my ppp IP with ifconfig) I use command like this: # /usr/local/bin/mailsirsmtp /var/qmail/alias/pppdir alias-ppp- solair.eunet.yu MyIP I get this: "tcpclient:unable to connect to solair.eunet.yu on port 25: host unreachable maildirserial:fatal:making no progress,giving up" I try to ping 194.247.192.52 and it is OK (194.247.192.52=ip of solair.eunet.yu) WHAT IS WRONG. How I automate process for sending and receive messages I do not try to get messages from my ISP PS: sorry for my bad english
