Message download settings

Is there a way to download only message headers? Is there a way to limit the size of messages (i.e. only messages under 500Kb)?

I answered it as a ticket 2511 at our official ticket support system.

Any chance of a public answer? ISP bandwidth limits mean big emails are a drag.

Hello,
we considered only adjusting server timeout, other features are not available.

OK,
Thanks for the response.
