[exim-dev] [Bug 1837] small subgroup attack

https://bugs.exim.org/show_bug.cgi?id=1837

--- Comment #9 from Jeremy Harris <jgh146exb@???> ---
FWIW, opinion from a security bod (H.Kario) was:

(question was "is a small-subgroups attack relevant to SMTP?")

"only if the SMTP server is configured to allow TLS connections only, for
opportunistic encryption not really. good to clean up, but not CVE worthy"
