well, netfilter works perfectly fine inside and outside a
guest, what you cannot do inside a guest is to manipulate
the netfilter rules

this is a kernel config option, you can select that when
you build your kernel and it will be there ...

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 :)

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 ...
