Request to unblock outbound SMTP (port 587) for app rialma-api

Hi Fly.io team,

I'm running a business internal management system (rialma-api) deployed on Fly.io 
and I need to send transactional emails (password reset, system alerts) via SMTP.

App name: rialma-api
Region: iad
SMTP server: smtp.kinghost.net
Port: 587 (STARTTLS)

Use case:
- Password reset emails sent to internal users
- System alert emails sent to internal administrators

This is a private internal system used by our company, not a bulk/marketing email sender.
We send a very low volume of transactional emails only.

Could you please unblock outbound SMTP on port 587 for our app?

Thank you.

this port is not blocked.
