Getting error: "Failed to send mail to<email-address>: unencrypted connection"

This is an issue with gomail - see here.

It causes failures when registering users on Microkubes when using the development/test setup with Mailhog.

In any case, I recommend we switch to a more maintained fork of gomail, like this one:
https://github.com/go-mail/mail

I've added ENV variable to control the behaviour - allowing unencrypted connections for development/testing setup.
To allow, you need to set the following ENV variable:

export ALLOW_UNENCRYPTED_CONNECTION=true
