Hi to all,
i want to use mailgun as smtp server for sending my emails but i'm unable to do it.
I've tried to configure it in all the ways possible but when i send an email test it waits a minute and then returns a page 404 error. I tried with acymailng 5 and 6 but it's the same thing.

Global site configuration:
Thank you in advance for an answer
