In order to keep our servers PCI compliant we've upgraded our SMTP outgoing mail service to 587.
You'll need to change your port from 465 or 25 in outgoing mail settings to 587. This is for Gmail, Outlook or any other email client you may be using.

Please, if prompted with security settings choose STARTTLS as opposed to SSL/TLS in Outlook for example.
