Debug response mail feature seems broken

[MKodde]

Context

While testdriving EB with Symfony 7.4, I noticed a 500 error on button clicking the Mail to OpenConext button on the debug page.

Where

• With your EngineBlock in dev mode
• Visit the EB homepage at: https://engine.dev.openconext.local/
• Perform a debug authentication by visiting the https://engine.dev.openconext.local/sp/debug/ page
• Choose an IdP on the WAYF
• Authenticate in Mujina
• You should now see the debug response page. Listing your attributes and other authentication data

Bug

• Click the Mail to OpenConext button
• You are sent to the user friendly exception page
• The logs show

{"channel":"request","level":"CRITICAL","message":"Uncaught PHP Exception Symfony\\Component\\Mailer\\Exception\\TransportException: \"Connection could not be established with host \"localhost:25\": stream_socket_client(): Unable to connect to localhost:25 (Cannot assign requested address)\" at SocketStream.php line 154","context":{"exception":{}},"extra":{"request_id":"69bba6bb08286","session_id":"3ba008e7ad0fecce40a4b833ced3952f"}}

Expected behavior

A debug mail containing the authn information should be sent to the site admin

⚠️ This might well be a dev only issue, but it also hints a possible greater mail problem. Please check other mail related features and fix accordingly.

We should probably use mailer_dsn: 'smtp://mailcatcher:25' in the parameters.dist, instead of mailer_dsn: 'smtp://user:password@localhost:25'
