I'm using Eudora.
I get a security error when I click on the link. Probably this has something to do with the way it's hidden in HTML, vs. the way Eudora can yank it out of plain text.
I don't like HTML messages ANYWAY because they go through
a UNIX shell account and I like to process them with procmail.
HTML mail, if used at all, should be a user preference option. It's not standardized by an RFC anyway, so different mail clients handle things like embedded links slightly differently. (And some mail clients don't handle HTML at all!)
Thanks,
Stan
