Has anyone successfully integrated MailHog into UF?

I’m trying to configure UserFrosting to send mail to the MailHog (https://github.com/mailhog) machine I’ve got running on port 1025. I’m having no luck with anything I’ve tried to date. Has anyone tried to do this and how did you succeed?

My custom default.php settings are as follows …
return [
‘address_book’ => [
‘admin’ => [
‘name’ => ‘Frank’
]
],
‘debug’ => [
‘smtp’ => true
],
‘mail’ => [
‘mailer’ => ‘smtp’, // Set to one of ‘smtp’, ‘mail’, ‘qmail’, ‘sendmail’
‘host’ => getenv(‘SMTP_HOST’) ?: null,
‘port’ => 1025,
‘auth’ => false,
‘secure’ => ‘tls’,
‘username’ => getenv(‘SMTP_USER’) ?: null,
‘password’ => getenv(‘SMTP_PASSWORD’) ?: null,
‘smtp_debug’ => 4,
],
…etc

Here is what I see output in the userfrosting.log from my latest effort …
