[Mailman-Users] problem with html emails with signature

[Χρήστος Ράμμος]

Hello all.
I came into a very strange condition.
I sent one HTML email with a signature to a Mailman mailing list without
having a footer and the email arrived well and perfectly signed.
When i tried to do the same but with the difference that i included one
or more reciepients in the CC field then the email arrived with broken
signature

The above problem came using Netscape/Thunderbird email client but when
i used MS Outlook Express then the signature was perfect!!!!!

Does anyone had any similar problem?

P.S.: i am signing this message too.. and making *bold and /italic /to
have some html things to see if it fails to your list too.!!!*
