SMTPS/SSL için Javamail ve Greenmail'i Kullanma

Question

Çalıştığım bir Greenmail sunucusuna SSL ve kimlik doğrulaması yoluyla ileti göndermek için JavaMail SMTP veya SMTPS kullanacak bir test yazmaya çalışıyorum. Ben isteyen kulüpler tam olarak ne yapması gerektiğini hızlı bir küçük alt yazdım

: Bakıyorum denedim

Sorunum birkaç istisna olsun olmasıdır

• JavaMail to send secure email through vps - SSLHandshake Exception, PKIX path building failed, etc. - Can't send mail
: burada birkaç diğer yanıtlara, ama bir şey eksik gerekirherhangi bir tavsiye için şimdiden uzun yazı ve teşekkür için üzgünüm Using JavaMail with TLS

PKIX path building failed: unable to find valid certification path to requested target

.

Answer 1

Böyle senin GreenMail sunucusunu başlamalıdır:

Security.setProperty("ssl.SocketFactory.provider", DummySSLSocketFactory.class.getName()); 
GreenMail mailServer = new GreenMail(ServerSetupTest.SMTPS); 
mailServer.start(); 

Answer 2

Greenmail sunucusunda kullanılan SSL sertifikası "bilinen" bir sertifika yetkilisi tarafından imzalanmalıdır VEYA sertifikayı Java'nın anahtar deposuna imzalamak için kullanılan CA sertifikasını eklemeniz gerekir. Java'ya, bilinen bir CA'ya kadar sertifika zincirini doğrulamamasını söylemenin bir yolu yoktur.
