```
public class SMTPSClient

```
SMTP over SSL processing. Copied from FTPSClient.java and modified to suit SMTP. If implicit mode is selected (NOT the default), SSL/TLS negotiation starts right after the connection has been established. In explicit mode (the default), SSL/TLS negotiation starts when the user calls execTLS() and the server accepts the command. Implicit usage: SMTPSClient c = new SMTPSClient(true); c.connect("127.0.0.1", 465); Explicit usage: SMTPSClient c = new SMTPSClient(); c.connect("127.0.0.1", 25); if (c.execTLS()) { /rest of the commands here/ } Warning: the hostname is not verified against the certificate by default, use setHostnameVerifier(HostnameVerifier) or setEndpointCheckingEnabled(boolean) (on Java 1.7+) to enable verification.

3.0

Modifier and Type	Method and Description
`protected void`	`_connectAction_()` Because there are so many connect() methods, the _connectAction_() method is provided as a means of performing some action immediately after establishing a connection, rather than reimplementing all of the connect() methods.
`boolean`	`execTLS()` The TLS command execution.
`String[]`	`getEnabledCipherSuites()` Returns the names of the cipher suites which could be enabled for use on this connection.
`String[]`	`getEnabledProtocols()` Returns the names of the protocol versions which are currently enabled for use on this connection.
`HostnameVerifier`	`getHostnameVerifier()` Get the currently configured `HostnameVerifier`.
`KeyManager`	`getKeyManager()` Get the `KeyManager` instance.
`TrustManager`	`getTrustManager()` Get the currently configured `TrustManager`.
`boolean`	`isEndpointCheckingEnabled()` Return whether or not endpoint identification using the HTTPS algorithm on Java 1.7+ is enabled.
`void`	`setEnabledCipherSuites(String[] cipherSuites)` Controls which particular cipher suites are enabled for use on this connection.
`void`	`setEnabledProtocols(String[] protocolVersions)` Controls which particular protocol versions are enabled for use on this connection.
`void`	`setEndpointCheckingEnabled(boolean enable)` Automatic endpoint identification checking using the HTTPS algorithm is supported on Java 1.7+.
`void`	`setHostnameVerifier(HostnameVerifier newHostnameVerifier)` Override the default `HostnameVerifier` to use.
`void`	`setKeyManager(KeyManager newKeyManager)` Set a `KeyManager` to use.
