My bad.. Sorry I'm new here and I don't get the terminology right. The
filter that tripped was in Privacy options/spam filters".

Ah, Ok -- I see the post and I'll try to figure it out and change the

It was a little "spammy" by our spam filter [Barracuda]. The listmembers
are *astoundingly* spam averse but [of course] I don't want to reject a
lot of false positives, so what I've done is set it up so that 'vaguely
spam-like' submissions are, in essence, moderated. In addition to
"hold"ing on "X-Barracuda-Spam-Status: Yes" I also hold on X-Barracuda-
Spam-Score: [other than zero]. This gets a LOT of false positives [a
spam score of 1.2 isn't very spammy, but it *might* be spam], so I just
send-em through if they're OK. BUT: if the message is too large, then I
don't want to send them through, even if the message was legit. so I
want the "you're too big" filter to bounce the message before the spam-
filter 'holds' it for me.
