[Enigmail] signature test

Hello list,

I just installed enigmail on thunderbird.  I am a university teacher and
I would like to use enigmail to have a means to prove that a message
sent to a student was really sent by me or that it has been tempered with.

I am a non-techie so I would like to know if somebody on this list
(which has been recommended for this purpose by the enigmail quick start
guide) could confirm that this message has been correctly signed; I have
the automatic signature option activated.

How can I now check and prove that this message has been sent by me and
has not been tempered with?

Thank you very much in advance,
Florence.
