Block bug for TLS?

[snpcp]

Code:
... MailConfig { host: xxx; port: xxx; ssl: false; connect timeout: 3000ms read timeout : 3000ms write timeout: 3000ms idle timeout: 6000ms }
Use tls port, but use setSsl(false), No event of ofFail() and thread blocked.

Version: vertx-core & vertx-mail-client 4.3.5
OS: MAC

the port is 465. it's TLS port, but not use setStarttls and setSsl.

@snpcp will it work for you if calling setSsl(true) ?

[snpcp]

yes, setSsl -> true, I see socket close ex.... it's normal.
I hope see exception, because port is TLS, but not handshake. so it must be ofFail.

[snpcp]

above all, don't block for anytime.

Look like not set SMTPConnection.errorHandler.

1. connect fail -> set errorHandler
2. read message -> set errorHandler
3. connect success & not handshake & close connect -> not set errorHandler

private void handleError(Throwable t) {
    context.emit(t, err -> {
      Handler<Throwable> handler;
      synchronized (SMTPConnection.this) {
        handler = errorHandler;
      }
      if (handler != null) {
        handler.handle(err);
      } else {
        if (log.isDebugEnabled()) {
          log.debug(t.getMessage(), t);
        }
      }
    });
  }
