In Thunderbird, for my e-mail account setup, I see

Server Settings:

Connection Security: STARTTLS Authentication method: Normal password

Other choices for Authentication are: - Encrypted - Kerberos - NTLM

What are the advantages of using Encrypted? (I thought STARTTLS was good enough)?

What do I need to do to enable encrypted passwords on my machine (RHEL, Sendmail)?

STARTTLS will still transfer your password encrypted over the wire. The 'encrypted password' settings will encrypt the actual password.

Personally I like STARTTLS because all the data transferred is encrypted, not just the passwords. Handy if I'm dealing with emails containing things I don't want random network lurkers to see.

Ah OK... so with STARTTLS, encrypted password option doesn't mean much... it already handles that. Makes sense... – NinjaCat Aug 7 '10 at 21:20
