Steffen is spot on: only the computer, where you create a tag, will 
display the new tag. If a tag with the same number but another label 
exists there, it will show a different label.

The tag is stored on the server, but it will not sync labels to other 

Besides, dovecot is probably limited to 26 tags (letters of the alphabet).

PS: I really liked to see a feature to limitlessly tag messages with 
arbitrary text strings from a synced, easily extensible vocubulary :) 
But storing them as headers might go against the idea of IMAP, to keep 
message pristine, storing them extra makes much buro-cracy, oh my!
