Swift_TransportException Failed to authenticate on SMTP server with username - php

Question

Hey awesome programmers!
Glad to see you all :)
This is my site... http://www.newdelhifreeads.com
I use cpanel.
This type of question has been asked but mine is a little different.
Whenever anyone tries to register on my site or try to post a free ad, the following error message results:
Swift_Transport Exception
Failed to authenticate on SMTP server with username "info#newdelhifreeads.com" using 2 possible authenticators
/home/newdelhi/public_html/protected/modules/Core/extensions/vendors/mail/vendors/swiftMailer/classes/Swift/Transport/Esmtp/AuthHandler.php(179)
167 foreach ($this->_getAuthenticatorsForAgent() as $authenticator)
168 {
169 if (in_array(strtolower($authenticator->getAuthKeyword()),
170 array_map('strtolower', $this->_esmtpParams)))
171 {
172 $count++;
173 if ($authenticator->authenticate($agent, $this->_username, $this->_password))
174 {
175 return;
176 }
177 }
178 }
179 throw new Swift_TransportException(
180 'Failed to authenticate on SMTP server with username "' .
181 $this->_username . '" using ' . $count . ' possible authenticators'
182 );
183 }
184 }

This might be old but somebody might get help through this. I too faced the same problem and received a mail on my gmail account stating that someone is trying to hack your account through an email client or a different site.
THen I searched and found that doing below would resolve this issue.
Go to https://accounts.google.com/UnlockCaptcha‎
and unlock your account for access through other media/sites.
UPDATE : 2015
Also, you can try this, Go to https://myaccount.google.com/security#connectedapps
At the bottom, towards right there is an option "Allow less secure apps". If it is "OFF", turn it on by sliding the button.
