Une fois qu'on a bien transpiré et configuré proprement son [serveur de messagerie](https://fr.wikipedia.org/wiki/Serveur%20de%20messagerie%20%C3%A9lectronique "Consultez l'article "Serveur de messagerie électronique" de l'encyclopédie libre Wikipedia"), comment vérifier s'il marche ? En écrivant un message ? Cela ne teste que la moitié du trajet, il serait bien d'avoir aussi une réponse... Si on a des copains patients, on peut leur écrire et solliciter une réponse mais c'est assez abusif.

TIO is a family of online interpreters for an evergrowing list of practical and recreational programming languages.
To use TIO, simply click the arrow below, pick a programming language, and start typing. Once you click the run button, your code is sent to a TIO arena, executed in a sandboxed environment, and the results are sent back to your browser. You can share your code by generating a client-side permalink that encodes code and input directly in the URL.

Should I Click uses a wide range of technologies, including machine learning, statistical analysis and security tools.
