Re: [Evolution] Server based filtering

Any 'server based' filtering will be what IMAP provides.  We have
thought about it, but only to the point of the 'too hard yet' basket.

What would that be useful for?  This really sounds like a client
issue.

Thats really part of your sendmail config (even in the case of 
imap, although you can use imap server filters to move big messages
somewhere else).

Definetly a client issue.

A mailing list configuration issue.  Which is already
part of mailing list software anyway.

Interesting.  Could be tricky to do.  Especially since mail servers
like sendmail have no concept of mail flags.  imap servers do mind you.

I'm not really sure this is appropriate for evolution, particularly
in its current state, as it starts to get into mail server
architecture, which evolution just isn't doing.
