I noticed that gmail does not recognize redmine emails as directed to me.

This is due to the following headers:
Bcc: , , , ,

1. Please notice that I can see the Bcc, which I should not usually be allowed to see.
2. There is no To: header.

I think that every time you send an email message you should add only To: header which should contain the destination address, and drop the Bcc header.

I can verify this issue.

Attached is an image of what is shown in gmail (I use Google Apps) and the raw email.

Hi Dan,

this is a public internet page therefore it is discouraged to publish other people email adresses. Harvesting is a fast and automated operation, so please remove at least the text file. Thank you.

If you want Redmine to use the "To" field, uncheck "Blind carbon copy recipients (bcc)" in application settings.

Hi Jean-Philippe, one point mentioned in the description hasn't been addressed. When I receive an e-mail from Redmine, I can see the 'bcc' field with everyone's e-mail addresses in. This field should not be visible in mail clients. When I send e-mails from my mail client ( on OS X), the recipients can't see the bcc field.

The point of using BCC fields is so that e-mail addresses aren't disclosed, but Redmine is disclosing them even when set to use 'bcc'.

Please can this be re-opened as a security issue? Because it means my e-mail address has been disclosed to many users as Redmine has sent out e-mails about tickets I'm interested in.

Thank you

Russell Hind
