> Over the past two days, I have been getting these messages that would

> getting dozens of those qmail-send failmails. Some of them are in
> Spanish or German. I have been just marking them as spam so I wouldn't
> see them but THEY'RE JUST TOO MANY, CAPTAIN!!!
>
> I've actually been thinking of writing a little script server-side to
> just archive them and give them to me in a weekly digest, and during bad
> spells like this I could just have it not send them at all.

> If plug-discuss doesn't have a better solution, that is.
