Autor: Robert Blayzor Data: Dla: exim-dev Temat: Re: [exim-dev] Feature: support for compressed messages on delivery
The attached patch is for proposed feature to allow Exim to ignore post transport_filter sizes (transport_count, transport_newlines). This allows the transport_filter to return binary data (such as compressed data via gzip, etc) and Exim will still use the pre-compressed message size in bytes and newlines. This avoids problems with applications that read in the message file data and expect/use the uncompressed message size. (so S= and W= maildir tags will match the uncompressed size). This will also allow Exim to use the pre-filter size values for quota computation. Currently only supported under the appendfile transport (maildirs), not sure useful elsewhere.
