Hi , Thanks Erwan,

Yes I did it.. what worries me is, that that instruction lsub "" * seems not to work.. I mean I am not allowed to see it

b lsub "" * b NO [NOPERM] No permission to read subscriptions (0.001 + 0.000 secs).

So not sure that this is the fault of Thunderbird :-) Thanks for your help

Have you tried

doveadm exec imap -o mail_debug=yes -u user

to get some more details why the NOPERM is given?
