com.Sun.mail.iap.protocolexceptionログイン方法はサポートされていません

JavaMailアプリとdovecot/postfix/muttは同じCentOS7物理サーバーボックスで実行されています。このJavaMailアプリは、サーバーでいくつかの変更が行われるまで、まったく同じコードを使用してIMAP経由でメールを確実にインポートできました このOpenVPNチュートリアルの手順を使用 。現在、アプリがIMAP経由で接続しようとすると、次のエラーがスローされます。

_com.Sun.mail.iap.protocolexception no login methods supported
_

サーバー構成を変更してIMAP接続を再度許可するにはどうすればよいですか？記録として、_dovecot.conf_には実際に_protocols = imap pop3_が含まれています

エラーをスローするコード行は次のとおりです。

_Session session = Session.getInstance(props, null);
Store store = session.getStore();
store.connect("Host", "user", "password*");//this line throws the error
_

完全なスタックトレースは次のとおりです。

EDIT＃1

MikeBの提案によると、_telnet mydomain.com 143_の結果は次のようになります。

_Trying 127.0.0.1...
Connected to mydomain.com.
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS LOGINDISABLED] Dovecot ready.
_

EDIT＃2

session.setDebug(true);を追加すると、スタックトレースの前に次の追加情報が出力されます。

_DEBUG: setDebug: JavaMail version 1.5.0-b01
DEBUG: getProvider() returning javax.mail.Provider[STORE,imap,com.Sun.mail.imap.IMAPStore,Oracle]

これらの新しいデバッグメッセージの直後に、上記と同じスタックトレースが続きます。

EDIT＃3

@masgaloehの提案に従って、私は_dovecot -n_と入力すると、端末は次のように応答しました。

_# 2.2.10: /etc/dovecot/dovecot.conf
# OS: Linux 3.10.0-123.13.1.el7.x86_64 x86_64 CentOS Linux release 7.0.1406 (Core)  
mail_location = maildir:~/Maildir
mbox_write_locks = fcntl
namespace inbox {
  inbox = yes
  location = 
  mailbox Drafts {special_use = \Drafts}
  mailbox Junk {special_use = \Junk}
  mailbox Sent {special_use = \Sent}
  mailbox "Sent Messages" {special_use = \Sent}
  mailbox Trash {special_use = \Trash}
  prefix = 
}
passdb {driver = pam}
protocols = imap pop3
ssl = required
ssl_cert = </etc/pki/dovecot/certs/dovecot.pem
ssl_key = </etc/pki/dovecot/private/dovecot.pem
userdb {driver = passwd}
_

これはソリューションの分離に役立ちますか？

dovecot -n output、「ssl-enforcing」モードを有効にしたようです

ssl = required

結果は、telnet 127.0.0.1143の場合のdovecot出力です。

* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS LOGINDISABLED] Dovecot ready.

'ssl-enforcing'モードでは、IMAPクライアント（javamailコード）はログインを行う前にSTARTTLSコマンドを発行する必要があります。 このスレッド から、JavaMailでstarttlsモードを有効にする必要があるようです。したがって、このコードを追加する必要があるかもしれません。

prop.setProperty("mail.imap.starttls.enable", "true")
