Hi,

I have a huge problem getting my mail-server up and running. Postfix is able to send messages. But i can't recieve a thing. i'm using squirrelmail (webmail) to send and recieve.
When i try to connect with telnet on port 25 i get the following message:
220 mail ESMTP Postfix

So that seems to be working.

So i believe there is missing one little thing somewhere in my config file, but i can't find the error.
Here you can find my config-file. http://www.digin.nl/problems/postfixmain.txt

Please help me,

Jaapdh

Your link does not work... also, output from /var/log/maillog would be helpful--why is the mail not being delivered?

Telnet to port 25 again, and issue the following commands:

Quote:
HELO <some domain>
MAIL FROM: <some working email address>
RCPT TO: <some local mailbox>
DATA
<some data, such as "this is a test">
. <a period>
QUIT

Basic mail received? If so, it's probably not your postfix configuration. In that case, the first two questions I would ask are:

1. Does this box have a valid A record, with an MX record pointing at it?
2. Does you ISP allow incoming traffic on port 25?

jkupski,

thanks for your help. I tried this, and recieved the basic mail.
The mx-record also points to my ip-address (have a look at dnsreport.com the domain is 2fifty4.nl).
Maybe the problem is because the mx-record is mail.2fifty4.nl?
The link to the config-file does work fine.

I will call my ISP tomorrow to ask if they allow. If they don't allow, is there a possibility to take another port for this?

thanks for your help

Well, your config looks ok as far as listening goes (inet_inferfaces=all), but port 25 isn't responding from the Internet.

If you're behind a router or firewall, check your port forwarding, however you have that set up. Naturally, check with your ISP to see if they're blocking inbound SMTP.

If they are, you can run Postfix on a different port, but you'll need a forwarding service like DynDNS.org to get the mail delivered. They'll receive your mail on port 25 and forward it to you on your selected port.

Ditto on lgarner's comments. Either your ISP is not allowing incoming traffic on port 25, or you've firewalled it off.
