Dave Bird seems to have associated key 0x329FB2ED (which belongs to Jon
Ribbens) with the address UKcrypto@chiark.greenend.org.uk (either
permanently :-( or temporarily). The combo box at the top of the message
has indicated that the message is to be encrypted. The destination box
at the top of the message has indicated the destination of the message.
He has then sent the message.

I understand that Dave Bird has had some difficulty routing incoming
messages from this list within Turnpike (probably because he doesn't use
the [rather fixed] SMTP envelope FROM address for that routing)...
However, I'm not entirely sure that this routing difficulty is in any
way relevant to the key association he has made.

Anyway - given this association between address and key, Turnpike has
then done what it is told - and has encrypted the message with the key
and then sent it. I don't think you can fault Turnpike for the sending
phase -- but it is proper to wonder at how the association of key and
address may have come about.

I can recall seeing this effect (misdirected encrypted messages) just
three times (in the two years since Turnpike 5 has included PGP
encryption) - and in each case Dave Bird has been the sender. 

Although I concede that many explanations are possible, a generic fault
in the Turnpike 5 user interface is not currently at the top of my list
of reasons for it happening.

[ObDeclarationOfInterest: I had a very significant role in the
development and shipping of Turnpike v1-v5]
