Send email

Python script:

```python # Import smtplib for the actual sending function import smtplib # Import the email modules we'll need from email.mime.text import MIMEText msg = MIMEText('My body') msg['Subject'] = 'My subject' FROM = 'algorithm@lemnoslife.com' msg['From'] = FROM TO = 'benjamin.loison@CENSORED.fr' msg['To'] = TO # Send the message via our own SMTP server, but don't include the # envelope header. s = smtplib.SMTP('localhost') s.sendmail(FROM, [TO], msg.as_string()) s.quit() ```

On my Linux Mint 22 Cinnamon Framework 13:

``` Traceback (most recent call last): File "", line 16, in s = smtplib.SMTP('localhost') File "/usr/lib/python3.12/smtplib.py", line 255, in __init__ (code, msg) = self.connect(host, port) File "/usr/lib/python3.12/smtplib.py", line 341, in connect self.sock = self._get_socket(host, port, self.timeout) File "/usr/lib/python3.12/smtplib.py", line 312, in _get_socket return socket.create_connection((host, port), timeout, File "/usr/lib/python3.12/socket.py", line 852, in create_connection raise exceptions[0] File "/usr/lib/python3.12/socket.py", line 837, in create_connection sock.connect(sa) ConnectionRefusedError: [Errno 111] Connection refused ```

On LemnosLife VPS no error or output is raised but do not receive an email on my personal email in a few minutes, even in spam.

s.sendmail returns {}.

The Stack Overflow answer 64890 solves this issue for my current needs it seems.

I verified with this method that can specify another email than the actual one for From for both Orange and Gmail.

Is:

conn.set_debuglevel(False)

useless?

help(conn.set_debuglevel)

Output:

``` Help on method set_debuglevel in module smtplib: set_debuglevel(debuglevel) method of smtplib.SMTP_SSL instance Set the debug output level. A non-false value results in debug messages for connection and for all messages sent to and received from the server. ```

help(conn)

Output:

``` Help on SMTP_SSL in module smtplib object: class SMTP_SSL(SMTP) | SMTP_SSL(host='', port=0, local_hostname=None, *, timeout=

[Benjamin-Loison]

    conn = SMTP(SMTP_SERVER)
    print(f'{conn.debuglevel=}')

conn.debuglevel=0

so it seems pretty useless.

Python script:

```python import sys # this invokes the secure SMTP protocol (port 465, uses SSL) from smtplib import SMTP_SSL as SMTP from email.mime.text import MIMEText SMTP_SERVER = 'smtp.CENSORED.fr' SENDER = 'benjamin.loison@CENSORED.fr' DESTINATION = 'benjamin.loison@CENSORED.fr' USERNAME = 'CENSORED' PASSWORD = 'CENSORED' # typical values for text_subtype are plain, html, xml TEXT_SUBTYPE = 'plain' content = '''\ Test message ''' subject = 'Sent from Python' try: msg = MIMEText(content, TEXT_SUBTYPE) msg['Subject'] = subject # some SMTP servers will do this automatically, not all msg['From'] = SENDER conn = SMTP(SMTP_SERVER) conn.login(USERNAME, PASSWORD) try: sendmailResult = conn.sendmail(SENDER, DESTINATION, msg.as_string()) if sendmailResult != {}: sys.exit(f'{sendmailResult=}') except: conn.quit() sys.exit('Sendmail error!') finally: conn.quit() except: sys.exit('mail failed; CUSTOM_ERROR') ```

[Benjamin-Loison]

try:
    print('Try')
    1 / 0
except:
    print('Except')
finally:
    print('Finally')

Try
Except
Finally

Can't send multiple emails without SMTP(SMTP_SERVER) and .login(USERNAME, PASSWORD)?

[Benjamin-Loison]

Python script sending multiple emails thanks to a function:

```python import sys # this invokes the secure SMTP protocol (port 465, uses SSL) from smtplib import SMTP_SSL as SMTP from email.mime.text import MIMEText SMTP_SERVER = 'smtp.CENSORED.fr' SENDER = 'benjamin.loison@CENSORED.fr' USERNAME = 'bloison' PASSWORD = 'CENSORED' # typical values for text_subtype are plain, html, xml TEXT_SUBTYPE = 'plain' SUBJECT = 'Email subject' def sendEmail(email, name): content = f'''Hello {name}!''' msg = MIMEText(content, TEXT_SUBTYPE) msg['Subject'] = SUBJECT # some SMTP servers will do this automatically, not all msg['From'] = SENDER try: conn = SMTP(SMTP_SERVER) conn.login(USERNAME, PASSWORD) sendmailResult = conn.sendmail(SENDER, email, msg.as_string()) if sendmailResult != {}: sys.exit(f'{sendmailResult=}') except: # [Benjamin-Loison/cpython/issues/54](https://github.com/Benjamin-Loison/cpython/issues/54) conn.quit() sys.exit('Sendmail error!') finally: conn.quit() USERS = [ { 'name': 'User A', 'email': 'user.a@example.com', }, { 'name': 'User B', 'email': 'user.b@example.com', }, ] for user in USERS: print(f'Sending email to {user["name"]}...') sendEmail(user['email'], user['name']) ```

I verified this script with my school email address for the sender and @orange.fr and @protonmail.com recipients.
