I use a Virtual Private Server, it is a Xen paravirtualised services and
has 768Mbytes of memory and 10G of disk and a single core, which I presume
is shared. It costs about ?27 per year. It uses a similar postfix
configuration as my main mail server, so it filters spam, viruses etc. It
is also possible to give it a list of valid email address, although I
haven't had the need to do that.

It was found through http://lowendbox.com/ which does have good deals
occasionally, if you get one before they sell out, I am not affiliated
with them in any way, except as one time customer.

openvz is not a great solution for SMTP, as things like fail2ban don't
work due to the shared nature of the kernel. Xen/KVM costs more, but is
more flexible for the kinds of stuff you want to do with SMTP.
