exim smtp connection limiting?

[WHN-Si]

Hi all,

Is there any way to limit the smtp connections from a single ip address?

We\'ve currently got a problem where a couple of users seem to be using multiple connection \"lets see how quickly we can increase server load\" bulk mailing programs, and I need a way of limiting the amount of mail that can be sent via smtp if possible.

Even if it just stops them opening multiple concurrent smtp connections, that would make a big difference.

any suggestions?

regards,

Simon

ok...just done a bit of homework on exim.org

These directives look promising:

smtp_load_reserve = 3
smtp_reserve_hosts = localhost
smtp_accept_max = 100
smtp_accept_max_per_host = 2

any comments on previous use and whether that will cap the problems we\'re having with run away exim processes due to the rare few overloading the smtp queue?

regards,

Simon
