Detailed steps to reproduce the problem?

The email-validator.validate_email (https://github.com/JoshData/python-email-validator/blob/main/email_validator/validate_email.py) call is failing after the pymongo update to 4.7.0.

When we debugged the cause for this we found out that there is an issue in loading "dns.resolver" module.

You can easily reproduce in REPL.

Below code gives the error "

AttributeError: module 'dns' has no attribute 'resolver'"

from pymongo.database import Database
import dns.resolver
dns_resolver = dns.resolver.get_default_resolver()

Where as below code works fine

import dns.resolver
dns_resolver = dns.resolver.get_default_resolver()

Even this code works fine (Here we imported pymongo after dns import)

import dns.resolver
from pymongo.database import Database
dns_resolver = dns.resolver.get_default_resolver()

Definition of done: what must be done to consider the task complete?

The below code must pass without any error

from pymongo.database import Database
import dns.resolver
dns_resolver = dns.resolver.get_default_resolver()
