I have a server CentOS 5.3 and WHM/cPanel 11.24 installed. In exim log files I noticed these wordings next to most of the emails.

Warning: Sender rate (a number, like 2.4) / 1h

Do you have any idea what it means?

cPanel has a ratelimit option on the exim configuration.

Basically it tells you for each IP address its send rate.

You can configure a maximum send rate per IP per hour (after which that IP is temporarily rejected, i.e. with code 4XX) to reduce the server load.

  • Is it possible to set ratelimit in exim.conf (I couldn't see that line) or cpanel only lets us to enable/disable this feature? – Ergec Jun 25 '10 at 12:28
  • @Ergec shure you can, take a look under "Advanced editor". I haven't access to a server at the moment to check where precisely is, but you should easily find it... – Daniele Santi Jun 27 '10 at 15:41
  • Can you please clarify exactly what the name of this option is. Like the O.P., I couldn't find an option that seemed to describe that behaviour. – Jeremy Visser Jun 16 '11 at 06:15

    @Jeremy Visser Go under `Exim Configuration Editor`, scroll to bottom and click `Advanced Editor`. Then *search* for the line `ratelimit = ...` (Ctrl-F ratelimit should suffice). For the parameters you can put there you should check the exim documentation at http://www.exim.org/docs.html . – Daniele Santi Jun 16 '11 at 11:25
  • And what does the `2.4` mean? Does that mean that IP address has attempted to send 2.4 times the limit? – Simon East Aug 07 '14 at 04:14
