Re: Python email problem (Ian Morris) ---------------------------------------------------------------------- Message: 1 Date: Wed, 14 Aug 2024 18:08:10 +0100 From: Graeme Gemmill<gra...@gemmill.name> To:dorset@mailman.lug.org.uk Subject: [Dorset] Python email problem Message-ID:<33492f48-e026-4998-a2cf-52ded7cc4...@gemmill.name> Content-Type: text/plain; charset=UTF-8; format=flowed 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 ------------------------------ Message: 2 Date: Wed, 14 Aug 2024 19:17:10 +0100 From: Ian Morris<i...@chirality.org.uk> To:dorset@mailman.lug.org.uk Subject: Re: [Dorset] Python email problem Message-ID:<ac4b556f-c02e-4fd3-a7dc-eb3ad7b45...@chirality.org.uk> Content-Type: text/plain; charset=UTF-8; format=flowed ?? ???? 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... ???)
< snip > Ian, thanks for your input. The SMTP settings in my Thunderbird setup include Authentication method: Normal password Connection security: SSL/TLS and as I said, I get the same error when sending to gmail.com No idea where to go from here. Graeme
