Hi, Rosie. FYI, this one came in with
Message was signed on 24/01/2008 23:28 with unknown key 0x87E4E875F91AD392.
The validity of the signature cannot be verified.
Status: No public key to verify the signature
Problems with bad signatures can occur on some mailing lists. For instance I
subscribe to many lists, two of which are Mandriva Expert and Mandriva
Newbie. On Expert my messages go through without a problem. On Newbie they
are often marked as bad. I understand that it happens when list-info is
added as a tail and some server setups are not configured to discount it.
Maybe that's a simplistic explanation, but it makes sense to me.
I think the occasional one has to be discounted, but if it is common on one
list you could put it down to the list-server.
