    I didn't make any changes to the SMTP settings and this just started happening.

    You missed the top portion of the stack trace.. and by chance, are you using a Google gmail account?

    I'm using mailgun. I don't see any errors being generated on the logs from there.

    Check the authentication data, make sure nothing is wrong with your mailgun account and make sure that none of their required settings (port #, TLS/SSL) have changed.

    I've tried changing the smtp settings to a different provider as well and having the same issues.

    Contact your host then.

    Something must have changed for it to suddenly stop working without any changes being made by you.

    Nothing was changed by us either and MailGun is working for others on the server.
