Hello list,

I'm using roundcube-1.3.3-1.remi.el6.

I've set up DKIM in my SMTP server.

The messages are being signed but are failing DKIM tests when I send in plain text from roundcubemail interface, but when I send the messages in html format from roundcubemail the messages pass DKIM tests. I'm testing by sending to a gmail account and port25.com, by the way.

In Thuderbird and Squirrelmail the messages do not fail. If also tested my DKIM with keys with the opendkim package 'opendkim-testkey' and they pass.

The the email headers have slight differences between those sent by Squirrelmail/Thunderbird and Roundcube in plain text.

Any help would be appreciated in resolving this...maybe a configuration setting?
