Opinions on qmail-spp patch please.

[Graham Miller <graham901@xxxxxxxxxxxxxxxxxx>]

Hi All,

I am looking at developing some plugins for qmail-spp. One is to provide the tcprules just as
tcpserver would. The other is greylisting. I realise that there are other ways to do this, but
the server environment I am in pretty much requires me to do it this way.

So I am interested in hearing opinions on the qmail-spp patch. At this time please ignore the
actual plugins ... I realise that being written by various people, each will have its own
performance and security issues.

I am asking here instead of the qmail-spp list to get varied opinions and not just those of
enthusiasts for the patch.

Specifically....

How badly does qmail-spp affect machinery utilisation? Especially as the email volume goes up. I
am interested in the overhead it may have just to consider doing something as well as the
running of plugins.

Does it (by itself) compromise security in any way?

Do you think it is acceptable to use if not spawning a shell for each plugin? i.e. plugins are
in C and fairly efficient.

Hope I get some interesting comments..

Thanks
Graham
