Initial and automatic email messages after setup

[labdir]

Am I correct in understanding that after a new setup, there are no automatic email messages at first? That is, neither the administrator nor any agents receive a welcome email or similar, and customers do not automatically receive an email when a new ticket is created? These automatic functions would have to be set up manually?
Does “Null mailer” mean that all messages are discarded?

In order for the account welcome emails to go out (e.g. to new workers), you'd need to have a functioning mail transport, and an outgoing address assigned to that transport that's used in Setup -> Mail -> Outgoing Mail -> Automated Email Templates.

For new ticket autoresponses, see https://cerb.ai/workflows/cerb.auto_responder/

"Null Mailer" is a mail transport that pretends to accept mail for delivery, but just discards it. It's used for testing.
