Here's a challenge. What's wrong with the following DTML snippet? <dtml-sendmail mailhost="MailHost"> To: <dtml-var email> From: Example.Net <WebStaff@example.net> Subject: Joining Example.Net To complete your registration with Example.Net (blah blah...) </dtml-sendmail> On my Zope site I had a similar DTML snippet, and it refused to send the mail message, but it also gave no error message that I could see, so debugging it took a ***long*** time. Do you see the problem? Here's what worked for me: <dtml-sendmail mailhost="MailHost"> To: <dtml-var email> From: "Example.Net" <WebStaff@example.net> Subject: Joining Example.Net To complete your registration with Example.Net ... </dtml-sendmail> Those double quotes can make a world of difference. I'm posting this to the Zope mailing list in the hope that it will keep others out of this blind alley which cost me so much time and frustration. Good thing my site is for fun and not for profit!
