The problem is, AFAIK, Thunderbird's autoconfiguration. It tries to
detect your SMTP settings (note: SMTP, i.e. for mail sending, not for
receiving, which would actually involve dovecot), but does it violating
the protocol (does pipelining without waiting for confirmation).

The bug is old and considered to be resolved. And nobody cares :(
If you use postfix a "workaround" is to temporarily disable postscreen,
which IIRC is the one (rightly) complaining about the improper pipelining.
