Summary: Need a random number generator
Product: Exim
Version: N/A
Platform: All
OS/Version: All
Status: NEW
Severity: wishlist
Priority: high
Component: String expansion
AssignedTo: nigel@???
ReportedBy: to.roma.from.eximbug@???
CC: exim-dev@???
An RNG has many applications. There are places where load balancing cannot be
achieved by standard Exim means, and other uses also.
For example, I need to fakereject a small random sample of spam for learning. I
need to have Exim bind to a random interface when sending outgoing messages.
Cryptographically signed return paths need random seeding.
A simple $rand, or $rand{MIN}{MAX}, would do the job quite well. Workarounds
like ($tod_epoch+$pid)%N, ${perl}, ${run}, ${readfile{/dev/urandom}} have
obvious problems.
TIA, Roman.
