I wrote a simple script to send an email via the Gmail SMTP server. Here the code:
import smtplib
msg = 'Hello World!'
server = smtplib.SMTP('smtp.gmail.com', 587) #port 465 or 587
server.ehlo()
server.starttls()
server.ehlo()
server.login('username@googlemail.com','password')
server.sendmail('username@googlemail.com','username@googlemail.com', msg)
server.close()
Sometimes it works and sometimes I get an error. What is the reason for it? I have configured Gmail for accepting less secure apps. If the error occurs I get the following message:
Traceback (most recent call last):
File "email.py", line 31, in <module>

I couldn't find any help on the internet. Many thanks in advance for every advice.
