I'm really sorry about this but I'm at a loose end with no one able to help. I'm also a bit of a newbie so bear with me.
I've recently moved web hosts, since then my Magento site is not sending out emails.
I'm using the SMTP Pro extension with an email address managed by google apps. Not sure if it's relevant but my domain name is managed by Fasthosts & I have the Google MX records in there (Unchanged since server move) and an SPF record (unchanged)
My new web host has not set up any domain records etc in cpanel (and I don't know how to do it) they're going to do this but are not convinced it will help the issue as they do not manage the domain.
The error I'm receiving is as follows:
SMTP Pro Self Test Results Sending test email to your contact form
address: admin@motif8.co.uk from: noreply@motif8.co.uk. Unable to send
test email. Exception message was: Incorrect authentication data
Please check the user guide for frequent error messages and their
solutions. Default templates exist. Email communications are enabled.
Required database tables exist.
I've tried a PHP script and it sent a test email without any issues, Magento permissions are all set as should be.
Before I moved host, my email settings within magento were 'localhost' on port 25, I've tried all manner of ports, all smtp.gmail.com variants and many different email addresses & passwords within our company (and some throwaway gmail accounts) to no avail.
Really hoping for some suggestions as I'm at a complete loss! Thanks!

Assuming that SMTP Pro is configure correctly and you hosting company is not blocking that port.
Log into your gmail account and follow the steps below.
Change your settings to allow less secure apps to access your account. We don't recommend this option because it might make it easier for someone to break into your account. If you want to allow access anyway, follow these
steps:
Go to the "Less secure apps" section in My Account.
Next to "Access for less secure apps," select Turn on. (Note to Google Apps users: This setting is hidden if your administrator has locked less secure app account access.)
