I am not finding the Apple Mail.app "Send Again" feature in the Web UI. The best I seem to be able to do with a message in the Sent folder is to Forward Inline, but sometimes I just want to resend a message again as it was originally composed without wrapping it in a forward.
I could try to use Send Again from Mail.app with my Zimbra account setup as an IMAP account but for some reason it is not syncing my Sent items all the way; email sent from the Web UI does not show up in Mail.app. Not a huge deal but I wondered if anyone else noticed this and whether there are plans to add Send Again later.
This is on 3.1.4 on RHEL 4, I did not check the 3.2 M2 beta yet.
