Problems with pgsql-announce

All,

1) I thougth we'd set up pgsql-announce so that it didn't bounce to the
sender?   I'm still getting 20-30 bounce messages every time I post to
-announce.

2) For some reason, I got four duplicate checksum warnings for *one*
posting to announce.  Example:

Duplicate posting detected
Duplicate Message-ID - <200701080946.29019.josh@postgresql.org> (Mon Jan  8
13:46:12 2007)
Duplicate Partial Message Checksum (Mon Jan  8 13:46:12 2007)

I'm certain that I sent the message only once, and it showed up on the list
promptly.  Huh?
