The Perfect Setup - Debian Woody (3.0)... sending mail from my XP box?

[ExCIA]

BTW... this is one of the best HOWTOs website I've ever come across. Two thumbs up.

Anyway, I have completed the 'The Perfect Setup - Debian Woody' and what do I need to do in order to send mails from my XP machines (outlook) to my Debian server and let the Debian server deliver the mail to my ISP?

I have three XP machines in the network and the forth one is the Debian server (192.168.0.3). All is connected through a router (broadband).

My ISP's (NTLWorld) smtp/pop3 servers are:

smtp.ntlworld.com
pop.ntlworld.com

To send mail I have to use SMTP authentication.

For example, if my email address is john.doe@ntlworld.com does that means I have to create an account on the Debian server as john.doe?

No, the user name doesn't matter, you could create a user named sampleuser with the password samplepassword.

Now you have to prepare Postfix for relaying through another server:

postconf -e 'smtp_sasl_auth_enable = yes'
postconf -e 'smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd'
postconf -e 'smtp_sasl_security_options ='


chown root:root /etc/postfix/sasl_passwd
chmod 600 /etc/postfix/sasl_passwd
postmap /etc/postfix/sasl_passwd
/etc/init.d/postfix restart

In /etc/postfix/sasl_passwd you put your ISP's SMTP server and a user name and password that are allowed to send through that server:

smtp.ntlworld.com   Username on smtp.ntlworld.com:Password

Whenever you change /etc/postfix/sasl_passwd you have to do the following:

postmap /etc/postfix/sasl_passwd
/etc/init.d/postfix restart

Now if you want to send email from your XP machine you tell your email client to use the user sampleuser with the password samplepassword along with your internal SMTP server (192.168.0.3).
And fetching emails doesn't change: you simply fetch them from your ISP's POP3 server (pop.ntlworld.com).

What is the difference between doing what you suggest and simply add an ISP's smtp server address in the 'relayhost =' in the /etc/postfix/main.cf file?


Good thing you mentioned /etc/postfix/sasl_passwd because mine doesn't exist, which I find that pretty strange?

Right, I forgot that one... You have to set the relayhost variable in /etc/postfix/main.cf:

postconf -e 'relayhost = smtp.ntlworld.com'

And don't forget to restart Postfix afterwards.

What if I don't have a password for my isp smtp, what if I just use the address?

If you dont have a password, just add the relayhosts line in main.cf

Great! I've been looking everywhere for this workaround!

I did every step, and I added relay = [smtph.sympatio.ca] to my .conf. However, postfix is still unable to send mail because of a 550 error. Here is my log:

Oct 5 13:18:08 localhost postfix/smtp[28537]: setting up TLS connection to smtp.bc.hotmail.com

Seems like the auth don't work..
Any i-d what I could do next?

You need to authenticate at the other mail server. Did you follow these instructions? http://www.howtoforge.com/forums/sho...07&postcount=2

Hi,

Is it possible that only selected users/domain can or will be relayed via relayhost?

Eg. user1@domain-a.com
user2@domain-a.com
user3@domain-b.com
user4@domain-c.com
user5@domain-c.com

then users under domain domain-a.com are relayed via relayhost
then user4@domain-c.com also get relayed...but user3 and user5 should not be relayed but get send direct to reciepients MX

It seems you can do it with the sender_dependent_relayhost_maps parameter (if you have Postfix 2.3 or newer): http://www.postfix.org/postconf.5.ht...relayhost_maps
