comment How does iptables execute rules?
Lines 1 and 2 above are in the same chain (on sequential lines) and lines 3 and 4 are on sequential lines in a different chain. If I've understood you correctly, if lines 1 and 2 above are in the same chain, and it reaches line 1, it will ignore line 2 - is that right?

comment How can I keep Apache from falling over?
I've had a look at Varnish and that looks like a good solution to dropping the CPU load, at least until I can move to a host with better CPU setup. Thanks.

Normally, something like 10-20 processes actively serving requests at any point. When the load is extremely high, then lots more. Magento is something of a monster to run, so while I would expect other systems to be ok with this traffic and setup, I can believe this might just be Magento outgrowing the box. Thanks for the book recommendation.

Sorry, didn't realise you'd edited your reply. Yes, it's a dual-core VPS (Xeon 2.4ghz). I would have thought this server should be able to handle its current load, which is why I'm worried I've missed something in config or have failed to spot a bottleneck somewhere.

comment How can I keep Apache from falling over?
First, thanks! The load is still pretty high, so I can try some of these things straight away, which is helpful :). I increased MaxRequestsPerChild to 4000 - load jumped immediately and stayed very high. I reduced it back to 1000, and the load has dropped somewhat, though still too high. APC is installed. SHM is 256. The include_once override is on.

comment How can I set up Postfix so that all email sent on my dev box gets routed to the developer email group?
All sorted - thanks rems! I had a couple of issues, which I'll outline here in case anyone else comes looking for this. I didn't realise what postmap was doing, first. So to do the above, I created a text file (/etc/postfix/canonical) with the first line from rems. I then ran postmap from the postix directory, and that generated a database file used by postfix (canonical.db). The line added to main.cf doesn't use the .db extension, but does look for the .db file. Finally you need regexp: instead of hash: if using a regex pattern as above.
