Outside the cyrus box: The Mimedefang milter has a built-in function
(optional of course) to remove an attachment, write it to a file, and
replace the attachment part with a text part giving a web link to the
file. The files could be on a slower type of disk drive than you need
for email storage

Yeah, odd! I wonder what's going on there. I'll take a look.

Okay, checked. Don't know where these things are used, other than expiry
and sieve, but at le
The sparse file idea is brilliant! Never occurred to me. :)
We'd have to store the reference-pointer in the message file, so we would
omit the actual attachment but eat up perhaps 50 bytes to keep the
reference to the file.
