To clarify, yes I see in the OP that the added 'real name' only
contains the local part, but it was quoted in the OP, so does or does
not the MUA put quotes around it?

In any case, I've tested

VERP_CONFIRM_REGEXP = r'(.*<)?(?P<addr>[^+]+?)\+(?P<cookie>[^@]+)@.*$'

against various forms, with and without quotes, and I think it's good,
but I'd still like more feedback.

I'v also tested all these:

VERP_CONFIRM_REGEXP = r'^(.*)?(?P<addr>[^+]+?)\+(?P<cookie>[^@]+)@.*$'
VERP_CONFIRM_REGEXP = r'(.*)?(?P<addr>[^+]+?)\+(?P<cookie>[^@]+)@.*$'
VERP_CONFIRM_REGEXP = r'?(?P<addr>[^+]+?)\+(?P<cookie>[^@]+)@.*$'

and only the first works (for cookie, but not addr). I'm not sure why
the second and third don't work, but they and the fourth all give

    raise error, v # invalid expression
sre_constants.error: nothing to repeat
