It also keeps track of GMail labels, that get embedded into the messages under the header X-Keywords (or whatever labelsheader is set to), and syncs them back and forth the same way as flags. The first time it runs on a large repository may take some time as the labels are read / embedded on every message. Afterwards local label changes are detected using modification times (much faster): """ Modification of message files as labels change? Ugh. I guess notmuch could read a user configurable header and apply the tags there, but notmuch modifying the message files is probably not going to happen. BR, Jani.
