Yes...this is the way I find more satisfying (intellectually), I have

  root@imap:/etc# grep postuser imapd.conf
  postuser: cyrus_shared_account

and

  grep root@mx:~# grep test.share /etc/mail/aliases.all
  test.share:                [email protected]

and on the server 

  127.0.0.1> lam shared.test_share
  cyrus_shared_account p

I've even try all right 

  127.0.0.1> lam shared.test_share
  cyrus_shared_account lrswipkxtecdan
  127.0.0.1>

but not success either

So as I understanding the text that should work. But It's not, when I send a
email I got 

  <[email protected]>: host
      imap.obspm.fr[/run/cyrus/socket/lmtp] said: 550-Mailbox unknown.
      Either there is no mailbox associated with this 550-name or you do not have
      authorization to see it. 550 5.1.1 User unknown (in reply to RCPT TO
      command)

      550 5.1.1 User unknown

I've check the postfix are correctly configure to use “+”.

And if I add

  127.0.0.1> sam shared.test_share anyone p
  127.0.0.1>

it's working


Big thanks for your help

Regards.
