Dear,
I followed those instructions: https://www.digitalocean.com/community/tutorials/how-to-install-postfix-on-centos-6
But it gives me a few qeustions.
I am using NodeJS
Postfix is just an MTA and not a full mail server. It allows the sending and routing of email but does not provide POP or IMAP services to retrieve mail or mailbox management. You will want to go with a more robust solution. We have a tutorial on setting up iRedMail which may be a better fit for what you're looking to do.
I tried this first but it's impossible because tar doesn't work
"tar jxvf iRedMail-0.0.0.tar.bz2 && cd iRedMail-0.9.0"
Gaves me:
tar (child): bzip2: Cannot exec: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now
To remove postfix and it's configuration files you can do an:
apt-get purge postfix
The error you are getting from tar indicates that bzip2 is not installed on your droplet. You can install it with:
apt-get update
apt-get install bzip2
Thanks it works but now there is a new problem my iRedmail does always use SSL https and i don't want to connect a SSL how do you disable that?
While I would recommend using SSL, if you need to disable it there is a thread on the iRedMail forums here that covers how to do this.
