User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624 I would like to be able to forward and reply to attached RFC822 messages. This would be an extension of the functionality introduced in the fix for bug 143565, though I am filing this as a bug rather than an RFE because I think it is a basic function. The Reply, Reply All & Forward buttons are greyed out when you open an attached RFC822 message in a window. How does this bite me? I administer several moderated yahoogroups mailing lists. Submissions to the list are forwarded to me by yahoogroups as attachments for approval. Sometimes I would like to query the submitter about something before approving or declining the message. It would be handy if I could use the "Reply" button on the toolbar for this, and if Mozilla would generate the correct In-Reply-To and References header for my reply to aid threading at the recipient's end. Reproducible: Always Steps to Reproduce: 1. Forward a plain text message to yourself as an attachment 2 [review]. "Get New Messages" to retrive the message 3. Open the attachment. Actual Results: The Reply, Reply All & Forward buttons on the toolbar are greyed out, as are the corresponding menu items. Expected Results: The buttons/menu items should have been active & functional.

Also, one cannot view the source of an attached RFC822 message. The View/Message Source menu item & the Ctrl + U hotkey are disabled.

unconfirmed ?? obviously valid....

Confirming => New in XP in 1.5 (post-PR2 nightly ~= 1.5 final); tweaking Subject. Bites me when I can't view headers of emails bounced to me.
