Centos 6とpostfix：SSH / telnetタイムアウトによる内部メール遅延

問題は、centOS 6がインストールされたVPSがあり、私のExchangeサーバーを除いて誰にでも電子メールを送信できることです。

4月29日 11:50:30 amazonnet postfix/smtp[16535]:2B6FF3CC49A:to=, Relay=gmail-smtp-in.l.google.com[173.194.78.26]:25, 遅延=1.1, 遅延= 0.06 /0.03 /0.27/0.73, dsn=2.0.0, 状態=送信(250 2.0.0 OK 1430308230 h9si43435938wje.62 - gsmtp)

4月29日 11:51:36 amazonnet postfix/smtp[16535]: 1AFB93CC49A: to=, リレー=なし, 遅延=30, 遅延=0.03/0/30/0, dsn=4.4.1, 状態=遅延(接続中) mail.amazonnet.hu[81.183.214.140]:25: 接続タイムアウト)

また、タイムアウトのため、SSH ではマイドメイン mail.amazonnet.hu に Telnet で接続できませんが、外部から Telnet で接続できます。
