Swift_TransportException Failed to authenticate on SMTP server with username

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

Answer 1

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.
