That worked like a charm, you are a life saver.🎊

While I have you, quick question - is there any configuration I have to do with mailgun (or mail server equivalent)? Right now the mails are still sent from mailgun with [mysite.co](http://mysite.co) email address, rather than from (the newly migrated) mysite.com.au.

I don’t mind if the emails come from [mysite.co](http://mysite.co), I’m more concerned as to whether there are any risk/unintended consequences if the domain names don’t match up between the forum and mailgun.

Thanks for the help, once again.
