Hy everyone, I just did the "The Perfect Setup - Debian Sarge (3.1)" Then I dit an error free install of ISPCONFIG. Set up the correct ports on the firewall. All looked well until i tryed to send and receive email. Checking out the forum everyone had different problems. And at least they had error messages, I DON'T!! It is hard to troubleshout without error messages. Here is the thing: I am able te receive email from everyone outside my domain. I can send my self an email I can send other users in my domain an email. I can receive email from other users in my domain. But I can not send email to others outside my domain, to firstname.lastname@example.org for example. The big problem here is that the email is send, thus gets out of my outbox. But I do not get a send error or a "could not deliver" or some other error?? It just disapeers??? The same thing hapens when I use webmail (so it can't be a local setting on my desktop). I have checked the the mail.log and there I see something hapening but I can not understand it. Mail.log: websrv1 postfix/smtpd: connect from unknown[10.0.0.150] websrv1 postfix/smtpd: 5B0D2D20C8: client=unknown[10.0.0.150], sasl_method=LOGIN, sasl_username=scarto websrv1 postfix/cleanup: 5B0D2D20C8: message-id=<004a01c6687d$8888b860$9600000a@winxp> websrv1 postfix/qmgr: 5B0D2D20C8: from=<email@example.com>, size=1343, nrcpt=1 (queue active) websrv1 postfix/smtpd: disconnect from unknown[10.0.0.150] websrv1 postfix/smtp: connect to yahoo.com[220.127.116.11]: server dropped connection without sending the initial SMTP greeting (port 25) Mail.log websrv1 postfix/smtp: connect to yahoo.com[18.104.22.168]: Connection timed out (port 25) websrv1 postfix/smtp: 5B0D2D20C8: to=<firstname.lastname@example.org>, relay=none, delay=31, status=deferred (connect to yahoo.com[22.214.171.124]: Connection timed out) Time out?? I have disabled the firewall on the server and only use the ports in the adsl-router. port 25/tcp, 110/tcp and just to be sure 143/tcp. If anybody would be so kind to tell me where to find the anwser for this problem, I would be verrrrry thankfull!!
