I've read a few suggestions & posted on Mozilla's forum & KB on how to protect email in only ONE acct in Thunderbird. No suggestions. So far, most methods aren't good if other users have administrative privileges, etc, or aren't secure at all, or are bit of a pain. I'm not worried about the CIA - just keeping personal medical correspondence, etc., out of view. Most messages won't be stored in the email client for long. Could use an encryption app (like TrueCrypt), but never used one. Read the manual - seems like a bit of trouble for this. How / where is the key stored - that is, unless you want to type it in every time? Suppose I could just not d/l the msgs for the private acct into T-bird, and only access the acct by webmail, entering (but not storing on PC) the password manually. Then delete msgs off the server. Maybe there are easier / more practical solutions? Thanks!
