[Dovecot] Rewrite the ostream output method, to save messages in another directory.

[Alex Baule]

Hi Timo,

I Trying to integrate my antispam with dovecot, using the imap folder to do
certain actions. I Do almost every thing, but i have some problems saving
the message.

Explaining this function, i try to use a imap folder like a "collector
folder", the user append a message from outside (ie another imap or pop
message) to this folder, and i don't want to copy this message, i need to
redirect it to another folder outside from user's maildir.

Well, i try to base it in zlib plugin, with  was the o_stream_create_gz().

Inside the o_stream_create_gz has the Output, it's a copy from the original
output.

I Try to replace this output, with another one, that i try to create to
another location, without sucessfull.

struct ostream *
o_stream_create_X_list(struct ostream *output, struct istream *input, const
char *type)
{
struct emexis_ostream *X_stream;
struct ostream *new_output;
int fd;

fd = open("/tmp/email",O_WRONLY);

new_output = o_stream_create_fd_file(fd, 0, TRUE);
o_stream_cork(new_output);

emexis_stream = i_new(struct emexis_ostream, 1);
emexis_stream->ostream.sendv = o_stream_X_sendv;
emexis_stream->ostream.flush = o_stream_X_flush;
emexis_stream->ostream.iostream.close = o_stream_X_close;
emexis_stream->output = new_output;
emexis_stream->input = input;

o_stream_ref(new_output);

return o_stream_create(&X_stream->ostream);
}


With this new o_stream, i got this error.

There is something wrong Timo ? Like missing something or i need to rewrite
another funcion ?

Tks  !!!
