Yes.

Userspace can't (shouldn't) cause kernel errors/warnings. Even if Dovecot did something wrong, I think it would still be a kernel bug if it logged a warning about it. And this doesn't seem to be a widespread problem, so I don't think Dovecot does anything wrong.

Probably not. I'd ask about this in your distro or kernel mailing list.
