[msmtp-users] msmtp as relay-only, accept from specified hosts, one account per host

[Jeff Kowalczyk <jtk@...1...>]

I need to relay SMTP alert emails from a program running on Windows PCs through
a Linux box on the DMZ, and out to the internet for delivery.

Is this functionality in scope for msmtp, or is the listening and relaying
local-origination only?

Apologies for such a rudimentary question, I've never configured or used msmtp.
Instead I deployed full postfix email servers with user mailboxes, etc.

Thanks,
Jeff
