I've heard that many versions of that script have vulnerabilities that
create an open relay out of your system.

Are these mails all to the same server?  Are the mails all identical?
There are several possibilities for why exim will stop at a certain
point.  One is that the receiving side said "enough for now".  That is
what the
    smtp_accept_max
    smtp_accept_max_per_host
    smtp_accept_queue
    smtp_accept_queue_per_connection
config options do (when exim is the receiving side).

The "remote_max_parallel" option may be relevant for your setup.  I
don't recall exactly which options are most helpful when attempting to
deliver a lot of messages, but it has come up on the exim-users list
several times.

The best thing, I think, if the messages are identical, would be to
give exim one message with a large recipient list.  Then it can
optimize handling of it.  For example, if multiple recipients are at
the same host, then exim can perform one SMTP connection with all
those users in the recipient list.

It means that at 21:34:48 (time) on March 1st, a message with id
16h0IK-0000Vm-04 was received.  The sender is "lance@augustmail.com".
The protocol was "smtp".  The host reported itself as "jakar" in the
HELO line, but it's IP (127.0.0.1) indicates the real name is
"augustmail.com" (via a reverse lookup).
