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?

/************************************My

• hdr, bool * matched, void *
  context) { DPRINTF("Func `%s' is called", __FUNCTION__);

     if (hdr && hdr->eoh == TRUE) { *matched = FALSE; }
     else                                         { *matched =  

  TRUE; }

     if (hdr) { DPRINTF("#%s: %s", hdr->name, hdr->value); }

  }

     if (count) { headers = (const char **)array_idx(headers_arr,  

0); }

     return i_stream_create_header_filter(stream,

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.
