Swift Mailer Module & Gmail SMTP

[chalorlay]

There was a problem communicating with SMTP: Authentication failed using username 'app@programs.my' and password '************'

Its been a week and was working perfectly earlier. Nothing was changed before the failure occurs. It just happens. Updated Swift mailer module (same version) as before, just in case, there's corruption in the codes.
