keine verbindung zum smtp von auserhalb möglich

Hallo,
ich habe meinen mailserver nach dem tutorial ISP-style Email Server with Debian-Etch and Postfix 2.3 eingerichtet, und es scheint auch soweit alles zu laufen. Über squirrelmail kann ich mich einlogen und mails empfangen sowie versenden.
Nun habe ich mir in Thunderbird das Konto eingerichtet, abholen der mails über IMAP mit SSL läuft super, nur kann ich keine mails versenden.
ein nmap auf den server ergiebt folgendes:
Code:
PORT     STATE    SERVICE
21/tcp   open     ftp
22/tcp   open     ssh
25/tcp   filtered smtp
80/tcp   open     http
110/tcp  open     pop3
143/tcp  open     imap
993/tcp  open     imaps
995/tcp  open     pop3s
1720/tcp filtered H.323/Q.931
5432/tcp open     postgres
8888/tcp open     sun-answerbook

auf dem server selbst:
Code:
PORT     STATE SERVICE
21/tcp   open  ftp
22/tcp   open  ssh
25/tcp   open  smtp
80/tcp   open  http
110/tcp  open  pop3
143/tcp  open  imap
993/tcp  open  imaps
995/tcp  open  pop3s
3306/tcp open  mysql
5432/tcp open  postgres

auf dem server kann ich mich über telnet auch einlogen:
Code:
meinhost:/home/user1# telnet localhost smtp
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 meinhost.domain.com ESMTP Postfix (Debian/GNU)
ehlo domain.com
250-meinhost.domain.com
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-AUTH PLAIN LOGIN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
quit
221 2.0.0 Bye
Connection closed by foreign host.
in der mail.log schaut dann auch alles normail aus:
Code:
Jan 26 14:20:34 meinhost postfix/smtpd[18976]: connect from localhost[127.0.0.1]
Jan 26 14:20:46 meinhost postfix/smtpd[18976]: disconnect from localhost[127.0.0.1]

beim versuch von ausen zu connecten bekomme ich nur:
Code:
max@mylaptop:~$ telnet meinedomain.com smtp
Trying 123.131.123.131...
telnet: Unable to connect to remote host: No route to host

obwohl nmap bzw. ping einen weg finden. in der mail.log ist vom dem versuch eine
verbindung aufzubauen auch nichts zu sehen.

hier noch meine postfix konfiguration, da ich denke dass der fehler da drinnen begraben liegt:

hat irgendjemand eine idee wie ich das ganze zum laufen bekomme ohne als open relay im netz zu hängen? also mails versenden nur über adressen die es auf dem system giebt usw.?

grüße aus italien

Code:
mynetworks=127.0.0.1/8
ist schonmal ein guter Anfang gegen Open-Relay. Nur diese Adressen werden ohne weiteres relayed. Will man.

Code:
inet_interfaces=all

stellt ein, daß der postfix auf allen Interfaces/Ips hört. Damit sollte eigentlich eine Verbindung von aussen möglich sein. Hast du deinen Postfix nach der letzen Rekonfiguration neugestartet?
 
Code:
mynetworks=127.0.0.1/8
ist schonmal ein guter Anfang gegen Open-Relay. Nur diese Adressen werden ohne weiteres relayed. Will man.

Code:
inet_interfaces=all

stellt ein, daß der postfix auf allen Interfaces/Ips hört. Damit sollte eigentlich eine Verbindung von aussen möglich sein. Hast du deinen Postfix nach der letzen Rekonfiguration neugestartet?

Hallo,

ja postfix wurde neugestartet und die symptome sind immer noch die selben.
Merkwürdig ist nur dass ich über telnet die restlichen serverdienste ansprechen kann (Bsp. dovecot mit imap).
irgendwelche anderen ideen?

Hi,

25/tcp filtered smtp

Prüf mal Deine Firewall.

-W

Hallo,
Firewall ist keine installiert.
Kann es sein dass mein provider die Packete filtert, da ich auch auf andere hosts ein filtered erhalte?
Wie kann ich testweise den port für smtp ändern?

Einige Provider filtern auf ihren Dialup-Bereichen den Port 25.

Was sagt denn ein
Code:
netstat -an | grep -i listen | grep 25

wie habe ich das nun zu interpretieren?

Das dein postfix richtig konfiguriert ist, allerdings von ausserhalb trotzdem nicht zugänglich ist. Da blockiert dann wohl ein Paketfilter.

Danke für deine Hilfe. Gibt es eine Möglichkeit den Port von 25 zu ändern? dann müsste ich halt mein Mailprogramm umkonfigurieren. Ich werde derweil versuchen in erfahrung zu bringen ob ein Paktetfilter bei meinem Provider oder beim Hoster läuft.

€dit:
Habe den Port in der /etc/postfix/master.cf vom smtpd auf 587 geändert, und nun kann ich mich von ausen verbinden und mails darüber schicken.
Nur werden nun keinne mails an meine benutzer mehr zugestellt , d.h meinbenutzer@meinedomain.tld bekommt keine mails mehr, auch in der mail.log stehen keine zustellversuche. sobald ich denn port wider auf 25 zurücksetze kommen mails an und werden korrekt durchgestellt. Wie löse ich nun am besten das Problem so,
dass mails zugestellt werden UND ich von ausen versenden kann?

Grüße max
