All subfolders are incorporated, besides Junk and Trash. There isn't any way to include these in the large dump, but they are often exported independently: for i in `cat emails.txt`; do zmprov ma $i zimbraSignatureName “`cat signatures/$i`”; zmprov ma $i zimbraPrefMailSignatureHTML “`cat signatures/$i`”; zmprov ga $i zimbraSignatureId > /tmp/firmaid; sed https://www.hostscheap.com/zimbra-migration-service
