I'm not sure in an ACL this will work since technically headers could be added in the transport/router itself. Therefore, there would have to be a way to get the actual message size BEFORE it's passed to the transport_filter. If that's possible, great, but I'm not seeing it.

And yes that's expected. But in the case of compression this will affect a couple of things. Quotas and maildir S= tags.

With compression, the message_size should be unchanged and to assume the input size prior to the transport_filter. (ie: transparent, assume no change in size)


I would think a setting to override this behavior may be needed. Something along the lines of "transport_filter_ignore_size = true" or something long those lines.
