smtp = smtplib.SMTP_SSL(SMTP_MAILSERVER)
smtp.login(SMTP_USER,SMTP_PASSWORD)
toaddrs = [send_to] + carboncopies
smtp.sendmail(send_from, toaddrs, msg.as_string())
smtp.close()
works for me. The mail server is siteground
(https://www.siteground.co.uk/); could the issue is that your mail
server (ionos) maybe doesn't support user/password authentication (e.g.
only supports OAUTH2 etc... ???)

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 = 'gra...@gemmill.name'
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
