Sign Message does just that. Inline OpenPGP, which you've used attaches the
signature to the end of the message. PGP/MIME attaches the signature as an

Attach Public Key attaches your key as apart of the message. It's one way to
distribute your public key to others, but IMNSHO, it's suboptimal. I believe the
keyservers are a better solution.

Had your key been on the keyservers, gpg would have automagically fetched it to
verify the signature on the message you sent to the list. Anyone replying
directly to you could then also send the reply encrypted to your public key.
So, you see, signing is sufficient after you've sent your key to a keyserver.

NB: As I said, I'm biased. I operate two keyservers and maintain the keyserver code.

There is no enigmail at mozdev.org key. Please *do not ever* send encrypted mail to
a public list _UNLESS_ the list is setup that way.
