AnnouncerPlugin probably should not set email_to as a recipient, or better document what it actually does

[anonymous]

From the documentation, it appears that the email_to preference is used to provide a custom To: address on emails that go out with recipients BCC’d, not as an email address to actually send emails to.

So, either EmailDistributor._add_recipient should not be called on this address, or the documentation should be updated to reflect the fact that unless this field is exactly "undisclosed-recipients: ;", the plugin will attempt to send all email to it.

Please upgrade to Trac 1.2, which has integrated the core of AnnouncerPlugin. Please raise the issue on the ​trac:MailingList if you encounter the issue with Trac 1.2.
