Добрый день.
Пытаюсь отправить email с помощью следующего кода и получаю ошибку
При этом в программе CryptoPro не используется, просто установлена на той же машине.
Подскажите, пожалуйста, с чем это может быть связано?

@Autowired private JavaMailSender mailSender;

...
final SimpleMailMessage email = new SimpleMailMessage();
email.setTo(recipientAddress);
email.setSubject(subject);
email.setText("Please open the following URL to verify your account: \r\n" + confirmationUrl);
email.setFrom(env.getProperty("support.email"));
return email;

... настройки
spring.mail.host=smtp.mail.ru
spring.mail.port=465
spring.mail.username=xxx
spring.mail.password=yyy
spring.mail.protocol=smtps
support.email=xxx@mail.ru
