IMAP sub-folders

[DougWare]

I use my Apache (with WM6.1) to connect to our company's Zimbra server using ActiveSync.

I also use an IMAP account to sync with my GMail for Domains. Although I can "sync" sub-folders (or in this case GMail labels), the mail program doesn't alert me to new mail.

I missed a moderately important message from a family member because I was unaware a new message had arrived in my "Family" folder.

Does anyone know if you can enable alerts for sub-folders?

Thanks,
Doug Eubanks
