I use fastmail.fm as a more powerful alternative to gmail. I use a rule to sort some of my work email out of the inbox to a subfolder. The inbox pushes immediately, but the work subfolder must be synced manually. Has anyone figured out how to have subfolders push in an imap client (gmail, or otherwise)?

Another problem I'm having is setting up an alias for the fastmail account so it looks like I'm responding from my work address. The reply to address field is not working.

Has anyone figured out these two issues? Thanks
