We have well working exim server 4.86_2 on rhel7.
Installed from source code.

Problems appeared when our servers get extreme highload, exim add extra address
to messages.
I have a lot of requests about it, that users got wrong messages.

Example (i choose that message, cause it is always sending for 1 address)

good behavior:
