Default Postfix SMTP Problem

I've installed following the perfect tutorial.
Everything is fine now except this : I cannot have the smtp running well

with netstat, I got :

Code:
tcp        0      0 0.0.0.0:25              0.0.0.0:*               LISTEN      18719/master

telnet localhost 25
Code:
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
220 mail.mydomain.net ESMTP Postfix (Debian/GNU)
and freeze

Any idea ? I really don't see the problem and need to be able to access smtp server through the internet

thx

possible problems:

***
myhostname = mail.mydomain.net

shouldn't be :

myhostname = mydomain.net

***
mydestination = mail.mydomain.net, localhost, localhost.localdomain

shouldn't be something like:

mydestination = /etc/postfix/local-host-names - you didn't gave info on what tutorial did you use so check that according to your tutorial

I'm using the tutorial
The Perfect Server - Debian Lenny (Debian 5.0) [ISPConfig 3]

and there is no postfix configuration part

I change to myhostname = mydomain.net
but I don't know what to put on my_destination

here is the point where postfix is installed:

http://www.howtoforge.com/perfect-se...-ispconfig3-p3

9 Install Postfix, Courier, Saslauthd, MySQL, phpMyAdmin, rkhunter, binutils

System mail name: <-- server1.example.com

should be something like server1.mydomain.net or just mydomain.net

same should go here:

vi /etc/courier/imapd.cnf
[...]
CN=server1.example.com
[...]

vi /etc/courier/pop3d.cnf
[...]
CN=server1.example.com
[...]

unfortunately i have different server configuration and cannot help you any further.

also same server1.mydomain.net or mydomain.net should be used in ISPConfig install

Full qualified hostname (FQDN) of the server, eg server1.domain.tld [server1.example.com]:

if there are some errors in logs you can post them so we can locate a problem.

if you used mail.mydomain.net everywhere instead of server1.mydomain.net or mydomain.net maybe you should change back to
myhostname = mail.mydomain.net

thx _X_ for your tips

I replace everything with myserver.myhosting.com
regenerate key.
Imap and pop with SSL are ok
but I still cannot connect to smtp ... will continue investigation ...

I got something strange,
If I desactivate my firewall, I can see port 25 on nmap but filtered and still cannot access to it

any idea ?

Your original main.cf file was absolutley fine. Please undo the changes that _X_ suggested in #2 as he has mixed up ispconfig 2 and ispconfig 3.

Please use something like mail.mydomain.net or server1.mydomain.net as hostname but not mydomain.net as this will cause a conflicht with the virtual domains otherwise.

Please post the output of

netstat -tap

and check your mail log for errors. Also contact your provider and ask them if they block port 25.
