XF 2.1 Unable to send mail

[Atmazphere]

Before I get told to check out the guide - I have. I have set up this plenty of times and I'm honestly stumped.

Error:

Swift_TransportException: Email to EMAIL@gmail.com failed: Unable to send mail. src/XF/Mail/Mailer.php:295

This error is instant, as soon as I try to send the email or a user awaits a confirmation, this pops up instantly.

It's a generic error message.

It could be due to the quota being exceeded, the account being restricted, etc.

You will have to contact your host and get them to investigate and resolve it.
