error while sending a form

[tskraft]

Hello,

the following error occurs when I send a mail via boltforms extension in bolt 4.

An exception has been thrown during the rendering of a template ("Connection could not be established with host "localhost:25": stream_socket_client(): unable to connect to localhost:25 (Connection refused)").

I appreciate any help.

@tskraft This isn't really an issue in boltforms, but in Bolt itself: Set up the mailer (in config.yml for Bolt 3, or in .env for Bolt 4)
