Hi @all,

I have a 3 server setup (MX ==LMTP==> Proxy ==LMTP==> Backend).

After upgrading to 2.2.18 I was able to use LMTPs from MX to the proxy but not from the proxy to the backend:

Received: from mf01.example.net ([172.17.1.5]) by mb01.example.net (Dovecot) with LMTP id T+LnDWrvcVWDSwAAJnBBGg for patrick@example.net; Fri, 05 Jun 2015 20:50:58 +0200 Received: from mx01.example.net ([172.17.1.5]) (using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits) zlib compression) by mf01.example.net (Dovecot) with LMTP id 8uuXJ13vcVW2fgAATr09kg

Can anyone help or is Dovecot not able to use LMTPs as client?

Regards Patrick
