How to set up a mailserver on Ubuntu 12.04 x86 1GB

I have added a domain to my control panel and I wanna create a mailserver.

Is 1GB ram enough or do I need something bigger? I don’t mind using only pop or smtp, but a webmail would be a plus.

I tried searching for the tutorial here but the search function is not working properly.

Just an FYI, you can’t use iRedMail or Zimbra any of the other ready made mail systems with an x86 OS, they all require x64. I went through this recently and just ended up installing postfix and dovecot by themselves and having my Gmail grab all the emails.

You can install it on an existing droplet along. However, if that droplet crashes because of running out of memory, or a kernel panic, or if your mailserver crashes because mysql is taking up too much memory and not leaving enough memory for the mailserver you’ll lose emails. <br> <br>If your current droplet has enough room for a mailserver, you can install it on it instead of a new droplet.
