I have multiple email accounts set up in Thunderbird 3.1.10 in Mac OS X 10.6.7, and have just installed latest GnuPG and Enigmail.
The Enigmail setup wizard helped me set up a Key for signing emails, and apparently it is tied to a "user ID" it created for one of my emails, say email address "A".
Question: If I send an email from my email address/account "B" in Thunderbird and sign it with the abovementioned key, will this email and its digital signature contain any information related to my email "A"?
I just don't want someone receiving emails from my address "B" to know anything about my address "A". Therefore do I need to create separate keys for all my email accounts" If so, how?
