How to limit the recipients per email?

[garconcn]

I have added the following rules in exim.conf a few days ago. I thought it could limit the recipients to 50 per email. However, I found one client can still send over 200 recipients in one email. Is there anything wrong? Thanks for any comments.

# Max recipients for each message
SMTP_MAX_RCPTS = 50
# Max messages sent in each SMTP connection
SMTP_MAX_SESSIONS_PER_CONNECTION = 50
smtp_accept_queue_per_connection = 50

Try this instead of SMTP_MAX_RCPTS = 50 :

recipients_max = 50
recipients_max_reject = true

Thanks. I will try this.
