Has anyone tried using MHonArc from a server-side include
(e.g. <!--exec cgi=[mhonarc command here] --!>)?
Don't know. But possible.
I'd like to use it like this for individual's mailboxes,
after presenting them with the daily news on a "home" page.
It may be better to be more specific on what you are trying to do. As
another user mentioned, using SSI can be expensive. Also, depending on
your intent, mhonarc may need to be invoked a particular way; mhonarc
may not be appropriate (or unable); or a better way is available.
