[Bug 1074542] Re: ban_list: addresses which begin with caret ("^")

Assuming there actually is such an address, it could be represented as
you suggest with a regexp that would match only the literal address.
E.g. if the address were "^some.name at example.com", the regexp would be
"^\^some\.name at example\.com$".

Escaping the leading ^ with a backslash wouldn't work without changes to
Mailman. Non-regexp matches on addresses are done by simple string
comparison which would treat the backslash as any other character.

I'm not convinced that this is a valid bug, but I'm marking it "Won't
Fix" so it can serve as documentation of how to deal with such an
