dovecotfeed unix is the normal configuration to define a lmtp client
that will forward emails to [9.9.9.9]:26

I've already done that but it did change the behavior.
You said it works as expected on your test machine, but did you try to
exactly reproduce my case ? ie : having 3 different users within 3
different domains all managed by Dovecot. User1 sends an email to
someone outside and CC user2 and user3.
Because, if I send an email from an outside account to someone and CC
user2 and user3, everything is working perfectly at Dovecot's side, even
if Postfix is launching a single process to deliver the email !

You're right, SSL is not working on Dovecot's LMTP. I need to remove
this setting.
