A variant of EmailStr that doesn't pass check_deliverability=False

[tamird]

Initial Checks

• I have searched Google & GitHub for similar requests and couldn't find anything
• I have read and followed the docs and still think this feature is missing

Description

See

pydantic/pydantic/networks.py

Line 742 in 07b6473

parts = email_validator.validate_email(email, check_deliverability=False)

. I would like to validate email addresses including rejection of unknown domains.

While we're at it, it would be nice to normalize as well.

Affected Components

• Compatibility between releases
• Data validation/parsing
• Data serialization - .model_dump() and .model_dump_json()
• JSON Schema
• Dataclasses
• Model Config
• Field Types - adding or changing a particular data type
• Function validation decorator
• Generic Models
• Other Model behaviour - model_construct(), pickling, private attributes, ORM mode
• Plugins and integration with other tools - mypy, FastAPI, python-devtools, Hypothesis, VS Code, PyCharm, etc.

Generally we try to discourage doing networking within validation, mostly because there's no way to do async in a validator.

[tamird]

That's a good point.

How about normalization?

@tamird,

Seems reasonable re normalization, but I think it makes sense to move this feature request to email-validator. Closing as not planned here for now!

[tamird]

email-validator already does normalization. it is not possible to use it though with EmailStr.
