And for some, once is more than enough. I don't use any spam filters,
as one false positive is more than enough, and I've seen many more than
one.
I'm not sure that a server really *has* to resend, but it still leaves
you with a problem: You can't reconfigure someone else's server. And,
you mightn't even be able to mail them to discuss it.
The point I was making, at the start, is to go into it with your eyes
open. Be aware that you may lose mail, important mail, permanently.
