Can you show me the valid line of "FROM" please.

Exim can not send mail (others servers do not accepts) only on auto replays.

If I change manually header file from:

xx-xx-x-H
Debian-exim 106 111
<>
1477166506 0

to:

xx-xx-x-H
Debian-exim 106 111
<mail@from>
1477166506 0

and exim -M id -> mail pass to send.

I changed transport from = "${local_part}@${domain}" -> from = ${local_part}@${domain}
same result (can not send the mail).

--------------


I looked at src/src/transports/autoreply.c and I saw only preparation of headers for mail.

But the line...

https://github.com/Exim/exim/blob/584ddd64e2f0caa3673bb219407e084826f5d965/src/src/transports/autoreply.c#L561

# pid = child_open_exim(&fd);

lead to...

https://github.com/Exim/exim/blob/584ddd64e2f0caa3673bb219407e084826f5d965/src/src/child.c#L190

# pid_t
# child_open_exim(int *fdptr)
# {
# return child_open_exim2(fdptr, US"<>", bounce_sender_authentication);
# }

As you can see second parameter is US"<>"

So I changed autoreply.c

and Exim do auto replays like a charm
