If you have a website, choose “Internet Site” if the configuration prompts ask for it. Use command “hostname” at the command-line to display your hostname if not sure.

Type telnet localhost 25 You should see: Hey my first email This is my first email on debian postfix after installing configuring it.

Denian end data hit enter, type in a dot, and hit enter again: Then quit You’re done. Type “mail” in the command-line terminal and see if you have some. Now let’s go to the next step: If you have a router with firewall, enable confiiguration 25 and forward that port to your computer.

Enter your MX records in your domain provider. From pulldown menu select “MX”. Type in your domain name ex.

You should see some records there. If you don’t see any MX records go back to previous step. You have to have MX record otherwise other computers won’t be able to see you when sending emails.

If your isp is blocking the traffic then you might need to login to their smtp services. This makes sure that any computer that tries to send an email to you has a valid domain name. This will stop them from spamming you.


If you want to add more anti-spam restrictions this is worth reading. Run this command to add virtual alias maps: Maildir has few advantages over mbox format.

It keeps emails in separate files, allows for multiple applications to read mail, etc. Now your mail goes to Maildir format.

Mutt If you want to read your new maildir format you have to tell mutt to use it as well. You should not postfix-to-mailman. You would get something like this: In that case mailman tries to send mails to:: Fall back to unsecure connections otherwise. It provides some sort of “compatibility mode”.

Secure data transfer is enabled but not enforced. If both sides agree the rest of the data transfer is encrypted, still using port They can be unset. See also the Debian bug report The secure layer is expected from the get-go and not an optional negotiated parameter after connecting. On Debian both names seem to be defined.

On Debian there is already a prepared entry for smtps but commented out. Remove the ” ” characters to enable it.

Not postgix be confused with fetchmail ‘s capabilities to fetch mails via TLS connections. One way to escape from this is configudation provide an unencrypted smtp service. Of course, this service should be available debin a local fetchmail process only. Fetchmail has to be configured accordingly via the option smtphost. User options user a It must be added to every user section.

Alternatively fetchmail can be instructed to use an external TLS-capable program 1 to forward mails. This is not handled here. And if fetchmail and Postfix run on the same machine it does not make much sense anyway.


Advanced options SPF and multiple external ip addresses Explanation I have some systems that are networked on an internal private ip address subnet These systems also share a public ip address subnet so they could email each other that way, but I’d prefer they didn’t for local addresses.

I have postdix SPF records for the public mail servers because all of our mail routes through those servers so if others care to check they can ignore email claiming to be from us but being delivered from other servers as per our SPF record. Recently I have expanded the ip addresses these systems are using externally to support multiple instances of port-based services like https adding: I could have expanded or added more liberal SPF record configuratino, or added more forward and reverse DNS records but I wanted to stick with less ip addresses.

So to recap my system has: Make SPF and multiple external ip addresses If you are trying to implement SPF records while binding to one external ip address and still working with dual-homed multiple ip aliased systems, or have any other reason to support multi-homed systems with multiple ip addresses but want to limit postfix to use only two of them try this.
