I'm having an error while trying to use javax mail dependency

I'm trying to use javax mail in my project. I have enabled less secure apps in Gmail and made an inbound rule to unlock the port 465.

This the configuration which I use in application properties.

''' 
spring.mail.host=smtp.hmail.com
spring.mail.username=dumitrachesabin@gmail.com	
spring.mail.password=mypass
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.socketFactory.port=465 
spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
spring.mail.properties.mail.smtp.socketFactory.fallback=false
support.email=dumitrachesabin@gmail.com
'''

Allowing the port:

I found on web that the port 465 needs to be unlocked, found a quick guide how to do that, you can see in the photo.

In the controller class I have set after the user is introducing his register credentials ( username , email address) to generate an email with a link to the edit profile page.

When I enter the username and mail and click submit I get the error
>"Unknown SMTP host: smtp.hmail.com;",

but the data is sent to the DB. I get error 500 on the web page.

@RequestMapping(value = "/newUser", method = RequestMethod.POST)
	public String newUserPost(HttpServletRequest request,
			@ModelAttribute("email") String userEmail,
			@ModelAttribute("username") String username, Model model) throws Exception {
		model.addAttribute("classActiveNewAccount", true);
		model.addAttribute("email", userEmail);
		model.addAttribute("username", username);

		if (userService.findByUsername(username) != null) {
			model.addAttribute("usernameExists", true);

			return "myAccount";

		}

		if (userService.findByEmail(userEmail) != null) {
			model.addAttribute("email", true);
			return "myAccount";

		}

		User user = new User();
		user.setUsername(username);
		user.setEmail(userEmail);

		String password = SecurityUtility.randomPassword();

		String encryptedPassword = SecurityUtility.passowrdEncoder().encode(password);
		user.setPassword(encryptedPassword);

		Role role = new Role();
		role.setRoleId(1);
		role.setName("ROLE_USER");
		Set<UserRole> userRoles = new HashSet<>();
		userRoles.add(new UserRole(user, role));
		userService.createUser(user, userRoles);

		String token = UUID.randomUUID().toString();
		userService.createPasswordResetTokenForUser(user, token);
		String appUrl = "http://"+ request.getServerName() + ":" + request.getServerPort() + request.getContextPath();

		SimpleMailMessage email = mailConstructor.constructResetTokenEmail(appUrl, request.getLocale(), token, user,
				password);

		mailSender.send(email);
		model.addAttribute("emailSent", true);
		
		return "myAccount";

Here I have the mail constructor class.

@Component
public class MailConstructor {
	@Autowired

	private Environment env;

	public SimpleMailMessage constructResetTokenEmail(
			String contextPath, Locale locale, String token, User user,
			String password) {
		String url = contextPath + "/newUser?token=" + token;
		String message = "\nPlease click on this link to verify your email and edit your personal information. Your password is:\n"
				+ password;
		SimpleMailMessage email = new SimpleMailMessage();
		email.setTo(user.getEmail());
		email.setSubject("Shop-Ufes - New User");
		email.setText(url + message);
		email.setFrom(env.getProperty("support.email"));
		return email;

	}
}

The error which I get in console is:

2020-10-03 16:57:22.256 ERROR 6952 --- [nio-8080-exec-7] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.MessagingException: Unknown SMTP host: smtp.hmail.com;

Your setup seems to be valid except of this

spring.mail.host=smtp.hmail.com

Seems like there is a typo related to the host name. I believe it should be

spring.mail.host=smtp.gmail.com
