My WAG? Comcast are logging all connections as SMTP regardless of encryption. > I have also noticed when sending through Yahoo/AOL (again, when it > works), even though the Thunderbird settings are set to use SSL or > STARTTLS, the receiving Yahoo server always receives it with SMTP. > Server mis-configuration there? If Thunderbird is configured to use SSL/TLS for a given account or outgoing mail server then the connections are always encrypted. Always. STARTTLS is opportunistic so connections might or might not be encrypted. -- Rich P. _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
