I was looking at the hardware requirements for Zimbra and am a little worried. My server only has 512MB of RAM.
I'm not looking to do more than probably 30emails a day. There will be maybe emails setup for 10 domains and I am the only user. All I need is a simple email server that is easy to setup: so far Postfix, Sendmail, Exim are not easy to setup.
I don't need the webmail, or any of the group messenging things.
I am wondering if I will really need the recommended 2GB of RAM for this. I am guessing that mostly all will have running will be the Zimbra Postfix MTA and the POP server. Does this really need 2GB for this?
