It's my code of message creation:
chunks = t_new(struct istream *, max_chunks);
chunks[cnt++] = header_filter(stream, &ra_mail->exclude_headers,
exclude_cnt); /* calls i_stream_header_filter */
#if 0
if (include_cnt) { /* calls i_stream_create_from_data for my
headers */
chunks[cnt++] = create_header_stream(&ra_mail->include_headers,
include_cnt);
}
chunks[cnt++] = create_stream_for_msgbody(stream); /* calls
i_stream_create_limit for message body */
#endif
chunks[cnt++] = NULL;
*stream_r = i_stream_create_concat(chunks);
if I enable the block of code, then header_filter_callback is called
for message body only. Why?
I reviewed `i_stream_header_filter' and noticed, that it returns
`i_stream_create(&mstream->istream, input, -1)' where `input' is
parent stream. Maybe, is it reason of problem?

Yeah, but it doesn't work without i_stream_seek(stream, 0) before.
How can I remove EOH after i_stream_create_header_filter (second
'\n')? Is it possible?
You can give i_stream_create_header_filter() a callback function,
which
gets called for each header line, and once for the EOH with hdr->eoh
==
TRUE. There you can set *matched = FALSE and it won't add the EOH.
