[(auto)Resolu]Postfix - cannot get RSA private key from file

Bonjour

J'ai installé un postfix + Dovecot + mysql sur mon serveur (13.04)
Je me suis largement inspiré de ce tuto https://library.linode.com/email/postfi … 0.19-mysql
J'ai obtenu un certificat ssl de StartSSL
Le premier bug fut pour la connexion en IMAP via Dovecot, my private Key ayant une passphrase, il ne pouvait la parser.. ce fut résolu en lançant dovecot avec l'option -p.. Plus de soucis en connexion imap.
Mais j'ai également un soucis avec cette même clef
que j’utilise également pour smtpd_tls_cert_file=

(J'ai vérifié la clef via openssl , ok)

voici un extrait de mail.log

Edit - Ne pas chiffrer la clef privée avec une passphrase qd on fait un certificat SSL pour Postfix
