Looks fine, but I would do s/(.*?>)(.*)$/$1/, so that 'test
[off-list ref] <#comment>' gets the second comment removed.

Yeah, but do you need to capture the second group?  IOW, like
"s/(.*?>).*$/$1/" perhaps?

I also thought about removing everything after first ">", but I will
not work for addresses like:

Cc: "foo >" <redacted> #v3.4 v3.5 v3.6

What about:

	$recipient =~ s/(.*<[^@]*@[^]]*>).*$/$1/;

or even

which uses regex used by 99% accurate version of extract_valid_address().

Of course, as you suggested earier, only the first email address should
be used, so in both cases the first ".*" should be changed to ".*?".
The second version becomes:
