Hi!
I have compiled all versions of mailutils, starting from 3.11 and up to 3.15,
on my two different PCs (Linux mint 20.3 and Gentoo x86_64): when processing a
simple rule (with maildir) for about 1350 emails starting from version 3.13,
the sieve process spends about 10 seconds (in version 3.12, about 0.5 seconds),
with 1 CPU core loaded at 100%.
My command:
sieve ~/.imail/sieve-to -f ~/.imail/sample/Sent
My rule:
require "fileinto";
if header :contains "to" ["sam...@gmx.de"]
{
fileinto "~/.imail/sample/test";
}

Best regards, Mikhail
