comment Outgoing emails not being encrypted
From the MX Toolbox output - a (probably large) part of your problem is that forward and reverse DNS do not match for the IP address of the mail server you are sending from - See en.wikipedia.org/wiki/Forward-confirmed_reverse_DNS

comment Outgoing emails not being encrypted
Is your domain name really "virtual.me" ? If so, SPF is not configured (and indeed, even your header above tends to indicate that - and that would contribute to the problem). There are a LOT of reasons your email may not be getting through - including blocklists (are you trying to send from behind a consumer DSL account ?), mail server with forward not using reverse etc.

comment Outgoing SPAM Protection for vps
(I downvoted the question because its not appropriate to this site - the question is to vague without knowing your usage case, and its not really a question for enthusiasts - although I sympathise with the problem of spammers). There is no conceptual reason that you can't monitor the number of connections on port 25 made through a system using KVM - Indeed I would expect the best place to do this would be at a router level which would be agnostic as to the VM technology. Blocking or transparently proxying port 25 traffic is entirely reasonable provided you advise your customers.

comment Allow SCP but not actual login using SSH
This is pretty cool - but I imagine it can be subverted by issuing a command which does an scp, then run a script afterwards !

comment Authenticating SMTP Proxy
Thanks for the comment. I dont have SSH access to old server, so I dont think that can work. I did find an smtp proxy I may be able to abuse to do the job, but it cant switch between backends based on domain/email which makes things a pain (and its not designed to be world facing)
