can not send mail

[provell]

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 blabla@yahoo.com 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[1215]: connect from unknown[10.0.0.150]
websrv1 postfix/smtpd[1215]: 5B0D2D20C8: client=unknown[10.0.0.150], sasl_method=LOGIN, sasl_username=scarto

websrv1 postfix/smtp[1219]: connect to yahoo.com[216.109.112.135]: server dropped connection without sending the initial SMTP greeting (port 25)

Mail.log
websrv1 postfix/smtp[1219]: connect to yahoo.com[66.94.234.13]: Connection timed out (port 25)
websrv1 postfix/smtp[1219]: 5B0D2D20C8: to=<scartomail@yahoo.com>, relay=none, delay=31, status=deferred (connect to yahoo.com[66.94.234.13]: 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!!

Is your server hosted in a datacenter or on a DSL line?

It's possible that if your server is at home, your ISP is blocking your port 25.
Which means that you can only send e-mail using the SMTP-server of your own ISP-provider. Like here in the Netherlands, most ISP's do so.
The reason is an anti-SPAM policy.

I do not say that it is your problem, but please check this out, it is good to know.

Hy geys, thanks for the response.

Yes, I am using an ADSL line and a certified router.

For the port isue I called my ISP and they sayd that the port should be open.
The even tested this and were able to telnet directly on port 25 to my postfix server.
So the port 25 blocked is defently not an isue here.

I have done some checking myself on the SMTP connection and read about a SMTP handshake.
My ISP is XS4ALL.NL.
The gave me a host/DNS name of SCARTO.XS4ALL.NL
I have named my server WEBSRV1 with the extension SCARTO.XS4ALL.NL
Thus the whole dns string to reach my postfix server would be:
WEBSRV1.SCARTO.XS4ALL.NL

This is dns string is not reachable from the internet and might be a problem for the "SMTP greeting (port 25)".
I wil try to change my host name from WEBSRV1 to SCARTO and wil do the same thing for my domain name.
From SCARTO.XS4ALL.NL to XS4ALL.NL.
(should have done that during installation of course)

As this server is not setup with ISPCONFIG would you be so kind to tell me what config files I have to change to make this happen?
Or is the advise to start all over again a better idea?

Then you must create a DNS record for WEBSRV1.SCARTO.XS4ALL.NL. Ask your provider to do so.

If you don't want to create a DNS record for WEBSRV1.SCARTO.XS4ALL.NL, then you must edit /etc/postfix/main.cf, /etc/hostname and maybe /etc/hosts. Restart Postfix afterwards.

XS4ALL is not blocking ports indeed.
I have XS4ALL at home too
