Original GitHub issue: https://github.com/modoboa/modoboa/issues/3609

Impacted versions

OS Type: Debian
OS Version: 12
Database Type: MySQL
Database version: 10.11.11-0+deb12u1
Modoboa: 2.4.3
installer used: No
Webserver: Nginx

Steps to reproduce

In modoboa's admin page got to Settings, then Webmail then SMTP settings then select "Authentication required"

Current behavior

The usage of this mode triggers an error 500 from /api/v2/webmail/compose-sessions with this message:

<html><body>

If I disable the authentication for SMTP, there is no such error but in my set-up, I prefer to keep the need for authentication when connecting through Postfix's ports.

The error is due to theses file I suppose:
/home/modoboa/env/lib/python3.11/site-packages/modoboa/webmail/lib/sendmail.py
/home/modoboa/env/lib/python3.11/site-packages/modoboa/webmail/lib/imaputils.py

Expected behavior

The mail should be sent and shall not trigger such request for dev mode as the variables are normally used only for testing purposes

#WEBMAIL_DEV_MODE = os.environ.get("WEBMAIL_DEV_MODE", "off") == "on"
#WEBMAIL_DEV_USERNAME = os.environ.get("WEBMAIL_DEV_USERNAME", "")
#WEBMAIL_DEV_PASSWORD = os.environ.get("WEBMAIL_DEV_PASSWORD", "")
