Restricting remote access with mailfront/CVM

[Scott Gifford]

I have a POP3/IMAP/SMTP server running mailfront and CVM. We'd like to
restrict who can log into it remotely, but I can't see a way to do that
within mailfront or CVM. Ideally I'd like to be able to restrict specific
users to logging in to SMTP AUTH, POP3, or IMAP from specific IPs

Is there a straightforward way to do this that I'm missing? Or do I need to
hack together some code?

Thanks,

-----Scott.

CVM is just a set of programs to check user's login/password against a
database and run a program in case they are match. So basically you
can modify your run-script so cvm module runs an IP checking script
instead of smtp/pop3 backend, and this script runs your backend if IP
matches as well.
