There are a number of lists, one has about 5K people on it. If I send
a message to one that has only 5 people on it, I see something like:

"webguru" is the name of this test list. The strange thing is that
we've been running for years with no problems. Yesterday, I was
getting errors with invalid character sets that seemed to be gumming
things up. I messed around with it to no avail, so I upgraded to the
latest version. I cleared out everything in process just to make sure
that nothing that hadn't been processed wasn't blocking everything
else.

When the problem was first reported, the logs looked OK to me, so I
told them there was a a delivery problem at their end. Then calls and
emails started pouring in, and I realized that I hadn't received any
messages even though I use gmail with no filters and I usually get
dozens of messages from one of our lists each day. I checked to make
sure we're not blacklisted and that seemed OK too. The weird thing is
that I can send email from the command line no problem, and
administrative messages (subscribe, unsubscribe, etc) seem to get
through just fine.
