Hmm...actually, I'm thinking this might be an RC problem or a possible compatibility issue between plugins.
I can view all the headers in the original message by clicking on the little arrow below the Date field. When I click on the forward button (not as an attachment), only the date, subject, to and from are there...rest of the headers are gone.
This use to work fine in Squirrelmail using the same imap server.
If I understand imap correctly, since the original message contains the full headers (viewable in the client..i.e RC), then the imap server has done it's job. It sent the message in it's entirety. It's the imap client's problem on how the message is handled after that, at least in regards to forwarding the message.
I'll run a couple of tests with something like outlook...see if it works ok.
I didn't see one but perhaps there's some option I missed to enable this in RC?
Apache 2.2.16
PHP 5.2.14
Cyrus-imap 2.3.16
Roundcube 0.4.2
Thanks,
