Question

Impossible to send emails from web service

Hello, I’m having trouble sending emails from my Python web service which runs on a Digital Ocean droplet (ubuntu 20.04). More specifically, I’m using the fastapi-mail library for sending emails, and I get the following error:

aiosmtplib.errors.SMTPServerDisconnected: Connection lost

The strange thing is that the same code works fine from my local machine, but it continuously fails from the Digital Ocean droplet. Do you have any suggestions?

Thanks in advance.

I’ve just found this Question and I think that I’m experiencing the same issue. I just opened a ticket in the Support Center.

Hi @campanamattia,

When configuring, you’ll need to add the following configuration in your conf file


conf = ConnectionConfig(
    MAIL_USERNAME = "YourUsername",
    MAIL_PASSWORD = "strong_password",
    MAIL_FROM = "your@email.com",
    MAIL_PORT = 587,
    MAIL_SERVER = "your mail server",
    MAIL_TLS = True,
    MAIL_SSL = False,
    USE_CREDENTIALS = True
)

Can you confirm you have added an actual Mailbox,password? Additionally, I’ll recommend using TLS,SSL and Credentials while port shouldn’t be 25 but 465 or 587.

Additionally, what you’ve found (the question you posted) is true so that might fix your issue as well!

If you provide me with a ticket number, I can try and escalate it from the community.
