EspoCRM 9.1.0 fresh install not sending email (system email)

[ChicagoGregg]

Hello,

I'm having issues with EspoCRM not sending emails. This is a brand new app installed, with its fresh configuration pointing to the system mail server (mail:2525).

The Cloudron email system is setup to use an Outbound relay with authentication. That part works (and has been working) just fine.

I'm testing by creating a new user and having the system send the user an email notification with the generated password.

While creating a new user, and clicking Save, it does not appear to send the email.

I have the Email Event Log GUI pulled up, the Service mail log, and doing a tail on the exim_mainlog on the destination server (Outbound relay host). None are showing the email go through.

One thing I notice is the info icon in Administration -> Outbound Emails -> System Email Address says:

"System emails will be sent from this email address. A group email account with the same email address must be set up and properly configured to send emails."

Going to the Group Email Accounts does NOT have a configured account configured by default (during application install/first time run). I enabled it as a "System" account with mail:2525, STARTTLS, and Auth unchecked.

While in the same configuration section, I go to SMTP and Send Test Email. I've tried entering an email for the same domain Cloudron is configured for as well as some personal email addresses of mine.

In the email logs (terminal, Service mail, I see:

And EspoCRM gives back an Error 500 Unknown error.

Anyone have any ideas?

Thanks!

550 I cannot deliver mail for <it@DOMAIN_HERE.net>

Did you set up a new account or anything with this domain? 🤨
