            Bug ID: 2537
           Summary: wrong value in $mime_part_count
           Product: Exim
           Version: 4.93
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: bug
          Priority: medium

Created attachment 1280

bash Script for reproducing

If a SMTP connection delivers multiple messages, $mime_part_count is not
properly reset and for non-MIME messages delivered after MIME messages
$mime_part_count is not -1 as it should and is documented: "For non-MIME
messages, this variable contains the value -1."

Could be easily reproduced with the attached shell script and the following
line in DATA ACL:

warn add_header = X-Exim-Test: $mime_part_count / $message_body_size

What the shell script it does:

Delivering four messages with batched SMTP:

(1) non-mime message
(2) mime message
(3) mime message
(4) non-mime message

Messages (1) and (4) are nearly identically, as well as (2) and (3).

Output:

$ ./multitest
check add_header = X-Exim-Test: $mime_part_count / $message_body_size
                 = X-Exim-Test: -1 / 46
  X-Exim-Test: -1 / 46
check add_header = X-Exim-Test: $mime_part_count / $message_body_size
                 = X-Exim-Test: 2 / 321
  X-Exim-Test: 2 / 321
check add_header = X-Exim-Test: $mime_part_count / $message_body_size
                 = X-Exim-Test: 2 / 321
  X-Exim-Test: 2 / 321
check add_header = X-Exim-Test: $mime_part_count / $message_body_size
                 = X-Exim-Test: 2 / 46
  X-Exim-Test: 2 / 46

--> $mime_part_count is wrong for message (4)! $mime_part_count should be -1
like in message (1).
