Après avoir fait beaucoup de recherches, j'ai pu envoyer des emails SMTP en utilisant le serveur gmail de Google. J'utilise le même code sans problème dans CPython sur Windows et Linux cependant quand j'essaie d'utiliser le code sur Micropython 1.9.2 (le plus récent au 11 septembre) sur le port ESP8266 ou Unix le code se verrouille sur la ligne 63 mais je Je n'arrive pas à comprendre pourquoi. Toutes les recommandations sur la façon de corriger ceci seraient grandement appréciées car je ne peux penser qu'à l'implémentation de SSL de Micropython et que je devrai essayer de porter le protocole SSL sur CPython.ESP8226 problème de connexion micropython ssl avec SMTP
Merci.
code Offending est:
61 heloCommand = 'EHLO Alice\r\n'
62 ssl_clientSocket.write(heloCommand.encode())
63 recv1 = ssl_clientSocket.read(1024)
64 print(recv1)

CODE MISE À JOUR AVEC RÉPONSE ACCEPTÉ (Oui , Je sais que c'est moche) avec read (1024) étant remplacé par readline() pour socket ssl. Également nécessaire pour ajouter un moyen de nettoyer le tampon après la commande EHLO ssl donc ajouté un "recvCount = recv1.decode(). Count ('\ n')" dans le premier EHLO puis une boucle dans le ssh EHLO pour le même nombre:

Merci pour votre perspicacité, a pris un peu peaufiner mais votre recommandation a fonctionné. Revoir la documentation ci-jointe (double merci). – jawbreaker79
