Problem connecting to an imap account with Dovecot

[Laurent Rathle]

Hello,

I have several accounts on my server. I can’t connect to one of them using Apple mail on Mac or IOS to create my account or read my mail in these applications. I can send mails to this address and read them with my Horde webmail. I have these messages in the log  :

I have :

Plesk 12
Ubuntu 14.04.2
Dovecot 2.2.12

You can see my configuration file here : http://pastie.org/10059309

What should I do ?

Thank you
