SendEmailError on SMTP with SSL : Connection unexpectedly closed

[galbini]

Describe the bug

During registration of a new user, the following exception occurred:

File "/usr/local/lib/python3.12/site-packages/fief/tasks/register.py", line 33, in run self.email_provider.send_email( │ │ └ <function SMTP.send_email at 0xffff79e47600> │ └ <fief.services.email.smtp.SMTP object at 0xffff785e1dc0> └ <fief.tasks.register.OnAfterRegisterTask object at 0xffff784750a0> File "/usr/local/lib/python3.12/site-packages/fief/services/email/smtp.py", line 60, in send_email raise SendEmailError(str(e)) from e └ <class 'fief.services.email.base.SendEmailError'>

To Reproduce

Steps to reproduce the behavior:

1. Configure Fief with SMTP with a SSL connexion ex : EMAIL_PROVIDER_PARAMS={"ssl": true, "host": "mail.infomaniak.com", "port":"465"}
2. Go to '/register'
3. Set form and Click on 'subcribe'
4. See error on logs

Expected behavior

A clear and concise description of what you expected to happen.

Configuration

• Cloud or self-hosted: self-hosted Getting start mode
• If self-hosted, Fief version: latest

Additional context

My SMTP config work with https://github.com/turbodog/python-smtp-mail-sending-tester
In your code, the SSL parameter seems used to configure tls but not ssl with SMTP_SSL object.

Yes, our SMTP implementation doesn't support SSL encryption but rather TLS encryption. This is something that has been reported a few times (not sure if/how we should fix this).

Try with the port 587 instead of 465, that should fix the issue.

Hello,
I try with port 587 but I was the next error
fief.services.email.base.SendEmailError: (550, b'5.7.1 Sender mismatch')

I'm not a python expert but i found the next sample code that's works

`
server = None
if options.usessl:
server = smtplib.SMTP_SSL(serveraddr, options.serverport)
else:
server = smtplib.SMTP(serveraddr, options.serverport)

server.set_debuglevel(options.debuglevel)
server.connect(serveraddr, options.serverport)
server.ehlo()
if options.usetls: server.starttls()
server.ehlo()
if options.SMTP_USER != "": server.login(options.SMTP_USER, options.SMTP_PASS)
server.sendmail(fromaddr, toaddr, msg)
server.quit()
`

If I understand the SMTP error 5.7.1 Sender mismatch, it means that the SMTP server rejected the From address you specified. Make sure to set the DEFAULT_FROM_EMAIL environment variable to an address authorized by your provider.

Thanks, that's work !
