Does the latest version of Mautic bundles a PHP wrap with Swift\_MailTransport?

Hi,

It seems that this might be an issue with not being able to connect using TLS rather than anything with Swiftmailer which works fine in 4.x releases. Have you double checked that you are using the correct SMTP credentials here, and that the port/authentication settings are as required by your provider?

rcheesley,

When the TLS tries to establish a handshake with the Google Firebase server, it is informed that “We do not authorize the use of this system to transport unsolicited, 220 and/or bulk e-mail.” I believe that Google is referring to the deprecated Swift\_MailTransport, which is available at [Swift\_MailTransport deprecated · Issue #866 · swiftmailer/swiftmailer · GitHub](https://github.com/swiftmailer/swiftmailer/issues/866).

Exists an email client, Mautic extension, OAuth 2.0 Client, or Mautic email API SDK.
