In order to confirm an action, I create an email message within a Python
Script that is considered junk by Outlook 365, using
s = smtplib.SMTP('localhost')
s.send_message(msg)
s.quit()
This works.
To prevent the "junk" categorisation, I therefore tried to use my 1and1
account as follows:
sender = '[email protected]'
addressee = sender
smtpaddr = 'smtp.ionos.co.uk'
port = 465
passwd = '*********' (deleted, known to be correct)
…….
with smtplib.SMTP_SSL(smtpaddr, port, context=context) as smtp:
smtp.login(sender, passwd)
smtp.send_message(msg)
(SORRY - indentation problem....)
This results in an error
smtplib.SMTPAuthenticationError: (535, b'Authentication credentials
invalid')
The same error message is given when I use a gmail.com account. In both
cases I know the password and username are correct
Can you help solve the problem please?
Thanks
