Voicemail to email does not go through and when I send a test email I get a 504 error. Sometimes the enter thing goes down and I have to restart PHP.
I tried using a self hosted email server that will likely be decommissioned soon and had no luck. I am now trying to use MailGun.
Any idea what settings is wrong? Password is copied from their site directly. smtp_from and smtp_username are the same value.

TIA!
