Thanks for the info/advice! I was mainly looking to use one of the
guests as a test environment. It's super-easy (and fast) to blow it
away and create a new guest from a ready-made template.
I see your point about a mail server trying to manipulate packet
targets. I believe it uses rules to do some form of tar-pitting. Any
time I can cause spammers grief and slow down their operations, I'll
take a look at it.

well, netfilter works perfectly fine inside and outside a
guest, what you cannot do inside a guest is to manipulate
the netfilter rules
I wanted to try to run XMail in a guest, but it needs netfilter
support, namely: CONFIG_IP_NF_TARGET_REDIRECT
this is a kernel config option, you can select that when
you build your kernel and it will be there ...
My guess is no-dice!
depends on what XMail is going to do with that :)
IMHO a mail server application which uses netfilter rules
to change the target of packets? sounds suspicious to me.
even more suspicious, if you run it on a guest with a
single ip for example :)
But I thought I'd ask if anyone's gotten XMail running in a guest.
we'll see, in case that doesn't work out, I'd suggest
to use something like postfix or qmail, which should
work perfectly fine for the mail part, and a few other
applications for pop/imap/webmail ...
HTH,
Herbert
Thanks,
