Mails are not going out in background.

We have backgrounds tasks working well in other endpoints. Any idea of what could be the issue?

We tried without a template (exactly like your example) and it does not work either.

class SigninEmailSchema(BaseModel):
    recipient: EmailStr
    a: str
    b: str


@router.post('/email/signin')
async def send_signin_email(
        bg: BackgroundTasks,
        contents: SigninEmailSchema,
    ) -> JSONResponse:

    message = MessageSchema(
        subject = ' subject ',
        recipients = [contents.recipient],
        template_body = {
            'a': contents.a,
            'b': contents.b,
        },
    )

    fm = FastMail(conf)

    #await fm.send_message(message, template_name='signin.html') # WORKS
    bg.add_task(fm.send_message, message, template_name='signin.html') # DOES NOT WORK

    return JSONResponse(
        status_code=200,
        content = {'message': 'email was sent'},
)

fastapi-mail ConnectionConfig does not need to check for a valid TEMPLATE_FOLDER value since pydantic's DirectoryPath already does that: https://pydantic-docs.helpmanual.io/usage/types/#pydantic-types

fastapi 0.70.0

Because fastapi-mail (1.0.1) depends on fastapi (>=0.68.1,<0.69.0) and no versions of fastapi-mail match >1.0.1,<2.0.0, fastapi-mail (>=1.0.1,<2.0.0) requires fastapi (>=0.68.1,<0.69.0). So, because hashjump co api depends on both fastapi (^0.70.0) and fastapi-mail (^1.0.1), version solving failed.

How do i use gmail alias with "MAIL_USERNAME"? Using gmail, i keep getting bad credential error.

What i'm trying to achieve is SportJom [email protected]

but that was not possible if my "MAIL_USERNAME" is not the email address.

For "MAIL_USERNAME" I have to use my full email address as the username. Is this just gmail issue?

Hello!

I'm using poetry and got an issue with TEMPLATE_FOLDER option with exception TemplateFolderDoesNotExist because it not pass path_traversal check.

After debug I found out that:

• base = Path(__file__).parent.parent inside path_traversal equals to PosixPath('/Users/netstuff/Sites/mailout/api/.venv/lib/python3.9/site-packages')
• passed to TEMPLATE_FOLDER path equals to PosixPath('/Users/netstuff/Sites/mailout/api/src/mailout/templates/mail')

What can I do with it? Thank you.

Please let me know what changes you'd like. I went back to RFC 2822 to check what I've done is correct, and I've tested with this version as a local package in my own project. It seems to work correctly but I would appreciate your advice.

I have run the tests but did not create the SMTP endpoint. I'm confident of my changes, though.

I'm trying to send an HTML rendered email with Jinja2 templates, but no context is being send.

Here's an example of the message I'm sending...

message = MessageSchema(
    subject="Grove Password Reset",
    recipients=[form.email],
    body={"email": email, "other": "some random string"},
    subtype="html",
)

fast_mail = FastMail(settings.EMAIL_CONFIG)

background_tasks.add_task(fast_mail.send_message, message, template_name="template.html")

The email is sent correctly, and the template shows up as a rendered HTML email, but none of the information from the body parameter gets rendered.

Hello, How can i send files from local directory? when i give a "./app/files/file.pdf" path, I receive this error:

AttributeError: 'bytes' object has no attribute 'read'

or

attachments field type incorrect, must be UploadFile or path

Hi, I created a function like this

async def email_simple_send() -> JSONResponse:
    email = EmailSchema(email=['[email protected]'])
    html = """<p>Hi this test mail, thanks for using Fastapi-mail</p> """
    message = MessageSchema(
        subject="Test",
        recipients=email.dict().get("email"),
        body=html,
        subtype=MessageType.html)  # subtype=MessageType.plain
    fm = FastMail(conf)
    # fm.send_message(message, template_name='email.html')
    await fm.send_message(message)
    return JSONResponse(status_code=200, content={"message": "email has been sent"})

How am I supposed to call it ? I tried this

def main():
    email_simple_send()
    return None

if __name__ == "__main__":
    main()

But I get this error

RuntimeWarning: coroutine 'email_simple_send' was never awaited  email_simple_send()

Any idea ? Thanks.

I am getting the following error when trying the first basic example here:

fastapi_mail.errors.ConnectionErrors: Exception raised (535, '5.7.8 Username and Password not accepted. Learn more at\n5.7.8 https://support.google.com/mail/?p=BadCredentials l33-20020a0568302b2100b005cdad9100desm5879477otv.40 - gsmtp'), check your credentials or email service configuration

MAIL_USERNAME=asd
MAIL_PASSWORD=<16-digit app password generated in gmail admin, 2step verification enabled>
MAIL_FROM=<matching email>
MAIL_PORT=587
MAIL_SERVER=smtp.gmail.com
MAILFROM_NAME=asd
MAIL_TLS=1
MAIL_SSL=0
USE_CREDENTIALS=1
VALIDATE_CERTS=1

I tried with personal mail/pwd for testing and didn't work. Then I tried with validated mail/pwd currently being used in production on another (flask) app and it didn't work.

A way to allow unit testing of application's email routes withpytestor unittest via mocking by fastapi_mail without actually sending out any emails.

application.py

conf = ConnectionConfig(
    MAIL_USERNAME = "YourUsername",
    MAIL_PASSWORD = "strong_password",
    MAIL_FROM = "[email protected]",
    MAIL_PORT = 587,
    MAIL_SERVER = "your mail server",
    MAIL_TLS = True,
    MAIL_SSL = False,
    TEMPLATE_FOLDER='./email templates folder',
    # if no indicated SUPPRESS_SEND defaults to 0 (false) as below
    SUPPRESS_SEND=0
)

fm = FastMail(conf)

@app.post("/email")
async def simple_send(email: EmailSchema) -> JSONResponse:
    message = MessageSchema(
        subject="Testing",
        recipients=email.dict().get("email"),  # List of recipients, as many as you can pass 
        body=html,
        subtype="html"
        )
    await fm.send_message(message)
    return JSONResponse(status_code=200, content={"message": "email has been sent"})

test.py

from application.py import fm

# make this setting available as a fixture through conftest.py if you plan on using pytest
fm.config.SUPPRESS_SEND = 1

with fm.record_messages() as outbox:
    response = app.test_client.get("/email")
    assert len(outbox) == 1
    assert outbox[0].subject == "Testing"

This will allow for more intuitive application mail testing via mocking and avoids bugging out email servers with dummy emails resulting in a potential block from that server, and this also eliminates the complexity of having to create a personal server to test sending outgoing mails.

This PR was heavily influenced by the Flask-Mail testing function

I use FastAPI-Mail and Celery to send notifications in the background. I want to place the static image in the template and send it to the customer.

I discovered that a url_for function returns an absolute URL and can be used in img tag as src.

The problem is that I get such an error, and I don't know how to solve it:

How can I solve this issue? Is there a better way to send a template with an image?

I want to use templates that are located on a different server, but I can not assign the path of remote folder to TEMPLATE_FOLDER. Here is the example path for a remote template that I wish to use:

https://raw.githubusercontent.com/smohadjer/slaven/master/app/content/email_templates/camp.html

Any idea how I can use this template for my email using TEMPLATE_FOLDER?

The same problem as in previous issue https://github.com/sabuhish/fastapi-mail/issues/157 but for the next version of the library. Do you consider to make less restrictive version dependency? 🙏🏻

1. Extra 'msgid domain' ConnectionConfig parameter

Set your own domain instead of the currently used local hostname.

MAIL_MSGID_DOMAIN: Optional[str] = None

2. Extra 'msgid domain' MailMsg parameter

Dynamically set your own 'msgid domain' together with the MailMsg parameters.

:param msgid_domain

Overrides MAIL_MSGID_DOMAIN parameter

3. Extra 'msgid' MailMsg parameter

Dynamically set the 'msgid' together with the MailMsg parameters.

:param msgid

Would it be possible to provide an example illustrating how to send an email with alternate plain text?.. as in the last example in these python email examples.
