To whom it may concern, Thanks so much for your good work and for adding the new feature (MailHost with asynchronous mode). I have just installed the new version of Zope (2.11.1) on my Mac to be able to use it. I did struggle a bit, though, because I didn't realize that in the method for sending email “mto” has to be a list and not a string, as it used to be. Is it correct? Maybe I'm wrong, but I couldn't find any indication for it in the documentation. It would be nice if you could add this, or clarify this point. One more little thing: in /MailHost/dtml/manageMailHost.dtml the two checkbox tags are not closed /> Thanks again and best regards, Giampiero
