[Woodcarver] Question about "invisible text"

[Alex Bisso]

My McAfee program is blocking quite a few e-mails that are posted to the
list, apparently because they contain "invisible text".  Does anyone know
what that is or how to get rid of it.  I do not recall who the earlier ones
that were blocked and deleted came from but the last one was from Glenda.  I
have a feeling that know one who is sending out messages with "invisible
text" know that they are doing it or that some anti-spam or anti-virus
programs stop them from being delivered.  I just recently figured out how to
look at e-mail that was blocked - was surprised how much it was..
