I think the other thing to consider is setting "smtp_accept_max = 10"
means you can only process up to 10 e-mails at one time. If you are
doing a number of checks, Virus, multiple blacklist checks - these tests
can take a while - possible a meaningful amount of seconds each. Just
bear that in mind. You probably want to increase"smtp_accept_max" quite
a bit. I've also changed my "log selector":
log_selector = +subject +incoming_interface +incoming_port +smtp_connection
(sits in the same config area as "smtp_accept_max = 10")
Now, when tailing the exim_main.log log file, you can see what the
"Connection Count" number is. I think you'll find this useful.
2017-01-25 11:04:50 SMTP connection from [S.S.S.S]:1188 I=[D.D.D.D]:25
(TCP/IP connection count = 3)
