I've marked several messages in Thunderbird using tags. Tags used are: 0 Important 1 Work 2 To Do 3 Personal 4 Later
The messages so tagged appear to have the flag fields set in the IMAP Maildir: cur/1449002162.8993_0.mail:2,Sb cur/1449001929.28087_0.mail:2,Sad I've looked in dovecot-keywords and find: $ more dovecot-keywords 0 $label1 1 $label2 2 $label3 3 $label4 I assume these "$label" values are macros that possibly refer to "Important", "Work", etc., but where are these $label's defined? Are they defined in the dovecot configs somewhere or does the mail client just "know" what these correspond to? --Mark
