Ah by the way, I tried the advice from theckman to check if my IP is blocking 25 by checking another mail server that certainly works.

Have you made sure your ISP isn't blocking outbound port 25? You can test this by seeing if another mailserver is blocked on port 25. I know for a fact mail2.linode.com should accept connections on port 25. Won't allow you to send mail, but TCP handshake should complete.

When I telnet mail2.linode.com 25 it works. So it seems that my IP is not blocking port 25.

What's your servers IP? Also post the content of your postfix configuration file.

Hi Obs,

server ip is: 176.58.103.37

here is the content of main.cf :

Debian specific: Specifying a file name will cause the first

line of that file to be used as the name. The Debian default

is /etc/mailname.

myorigin = /etc/mailname

smtpdbanner = $myhostname ESMTP $mailname (Debian/GNU)

biff = no

appending .domain is the MUA's job.

appenddotmydomain = no

Uncomment the next line to generate "delayed mail" warnings

See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for

information on enabling SSL in the smtp client.

What's the output of grep ^vmail /etc/group /etc/passwd; ls -l /home | grep vmail

Hi,

the output of that command is:

$ grep ^vmail /etc/group /etc/passwd; ls -l /home | grep vmail

/etc/group:vmail:x:5000:

/etc/passwd:vmail:x:5000:5000::/home/vmail:/bin/sh

drwxr-xr-x 2 vmail vmail 4096 Oct 11 20:40 vmail

Well the error Oct 12 03:36:07 (none) postfix/master[20444]: fatal: /etc/postfix/master.cf: line 111: bad transport type: user=vmail:vmail is why it's not starting, however you do have the vmail user and it looks fine.

I don't have a debian box handy to test the tutorial out on, I'd suggest try running through it again maybe you missed a step. If that doesn't work post the contents of your /etc/postfix/master.cf

Typically "transport type" would be "unix" here; it's the second parameter of the master.cf entry.

Two guesses:

1) Leading spaces have got lost in the second line of the "dovecot" entry and so it thinks it's a new entry

2) An error in the line above
