some kind of a mismatch between the way I generated the password
with doveadm and entered it in passwd.db and the way I entered the
non-hashed password into the password field in the new account
section of Thunderbird.It means that dovecot expacts to verify a 32 byte long password
hash. What it detects has a size of 0 byte. You haven't shown an
example line of your passwd.db file, but I would guess you build it
up not correct.See

Thank you for your reply. My /etc/dovecot/passwd.db shows:
test@domain.com: {SHA256}tdA2DIOZhwLOKVxA2WiOY0oy9GB8A6baW/okY+DTFi0=
I'm not sure what could be wrong with this file. It is a plain text
file created in vim.
Permissions:
-rw-r--r-- 1 root root 70 Jul 23 19:14 /etc/dovecot/passwd.db
In Thunderbird, I simply enter the text equivalent of the SHA256 in
the "password" field when creating a new account.
Do you - or anyone else - have another suggestion? Many thanks!
