Aloha, The Zope (2.7.5) API docs for MailHost show this for simple_send: -------------- simple_send(self, mto, mfrom, subject, body): Sends a message. Only To:, From: and Subject: headers can be set. The arguments are: mto A commaseparated string or list of recipient(s) of the message. mfrom The address of the message sender. subject The subject of the message. body The body of the message. -------------- So it reads like it can handle more than one To: address, something like this comma-separated string: 'me@mine.com,you@yours.com,him@his.com' ...but when I do this the message only gets sent to the first address in the list. Is this a mistake in the docs - do I need to use send() to send to multiple addresses? Or is there something wrong with my comma-separated string of recipients? Or is there a third possibility I haven't even considered... :-) thanks, John S. -- John Schinnerer - MA, Whole Systems Design ------------------------------------------ - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration john@eco-living.net http://eco-living.net
