Python

import os

SERVER = os.environ.get("SERVER", "<your-smtp-endpoint>")
PORT = int(os.environ.get("PORT", 25))
SMTP_USERNAME = os.environ.get("SMTP_USERNAME", "<your-username>")
SMTP_PASSWORD = os.environ.get("SMTP_PASSWORD", "<your-password>")
SENDER = os.environ.get("SENDER", "noreply@<your-domain>")
RECIPIENT = os.environ.get("RECIPIENT", "<recipient>@aboutmy.email")

msg = MIMEText("This is a test message.")
msg["Subject"] = "SMTP Test"
msg["From"] = SENDER
msg["To"] = RECIPIENT

with smtplib.SMTP(SERVER, PORT) as smtp:
    smtp.set_debuglevel(1)
    smtp.ehlo()
    smtp.starttls()
    smtp.ehlo()
    smtp.login(SMTP_USERNAME, SMTP_PASSWORD)
    smtp.sendmail(SENDER, [RECIPIENT], msg.as_string())

print("Mail queued successfully.")
