Re: [opensuse] Is it possible to send email with postfix without DNS?

I wanted to, previously, because setting up bind is such a hassle... and
because the machine is very low on ram.


The machine from the Closet of Anxieties under my desk, the single core 800MHz job that supports, as I said, Bind/DNS, DHCP, fetchmail, VNC server and xfce, SSHD, Postfix, Dovecot and NFS, is now running with just 500M[1]. I saw the load average go up to this morning while running fetchmail though spamassassin, 16 NFS mounts active, mail flowing out. It actually reached 0.9.

This machine is running Mageia with a 3.4.52 kernel. Perhaps its that Mageia is dramatically more efficient than openSuse :-) :-) :-)

So I think you underestimate the capabilities.
Either that or you are basing your estimates on one of
a) how MS-Windows performs in similar situations
b) how a Linux machine that is overloaded running X performs

Having encountered (b) I can sympathise. Bus the kind of server I'm talking about is headless and doesn't need X. Heck, this one doesn't need VNC :-)

[1] The other 500M is in another CoA machine I'm commissioning
A: Yes.
