That one came through, okay. Having a look at the source of the message, the list added it's signature as another section to the mail. The different parts of the mail have individualised headers that tell each section apart, as well as which parts are associated with each other. And, by the converse, the boundary marker provides a division that is to be regarded separately. The signed portion of the message, is just that: It's a *portion* of the message that's signed. It has to work that way, as the headers will change in transit. And, as we see on lists, footers can be added. So a signed message doesn't authenticate the entire posting, just some portion of it. Unfortunately, the mail client doesn't indicate which parts are verified by the signature. Nor does mine indicate that only some portion of the message is verified. It's probably possible to forward someone's signed message, add stuff below the signed content, and fool people. -- [tim@localhost ~]$ uname -rsvp Linux 3.9.10-100.fc17.x86_64 #1 SMP Sun Jul 14 01:31:27 UTC 2013 x86_64 (always current details of the computer that I'm writing this email on) Boilerplate: All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I only get to see the messages posted to the mailing list.
