Mailscanner and server load

[Martin Hepworth]

<x-flowed>
Hi

you don't mention how many emails a day you are processing or what extra
SA rule you have (and whether using any RBL's in SA).

You also don't mention what "Max Children" setting you have - this can
have a big impact on load..

when you upgrade it will spike first of all as it's got all the backlog
to process.
