[Zope] mail host question

I am having some problem configuring zope mail to work properly, particularly with PTK v 0.7.1. When I logon as a new member, its says "successful", but I get no mail to confirm my logon (I did get it to work once but don't know how). I have the smtp host set to an IP address for an smtp mail server. I tried a couple of others by name such as "mail.domain.com" but got an error relating to needed/missing "domain" The permissions on the various zope security screens has all possible users set to "use mail host" Sean Kelley Prompt Software, Inc. www.promptsoftware.com sean@promptsoftware.com voice: (415) 382-8840 fax: (415) 382-8868
