FT_NNTP

NNTP (Network News Transfer Protocol) protocol filter.

Category: Protocol filter

Supported flags:

FF_READ_ONLY_IN
FF_READ_ONLY_OUT

Object types:
OT_NNTP_ARTICLE - incoming news message
OT_NNTP_POST - outgoing news message

Indicates object parts: no

The objects contain a news message in one stream.

During receiving an incoming message for filtering (not in read-only mode) the library sends X-WAIT: 0 custom header to mail client each 15 seconds to avoid breaking the connection by timeout. These headers are ignored by NNTP clients.

It makes sense to use FF_READ_ONLY_OUT flag, because the news clients usually have small timeouts, and can break the posts during filtering a large message in dataAvailable event.
