[kurt c]

I don't know if this is more of a ThunderBird question. I have already
changed this dummy kurtc name to my real name lawrence in the setting of
my Gmail account, but somehow on this mailing list I still appear as
"kurtc". I read it's because the outgoing server name is still under the
name of "kurt c", and this outgoing server name can be changed under the
"Tools" dropdown list. But somehow I don't see any outgoing server
choice under the "Tools" section of my Enigmail. Can anyone give me some
idea?

Thanks.
