AttributeError: module 'yagmail' has no attribute 'SMTP'

[cheraghiam]

When trying to initialize the SMTP client using yagmail.SMTP(), I receive the following error:

AttributeError: module 'yagmail' has no attribute 'SMTP'

This occurs even though there is no local file named yagmail.py, email.py, or smtplib.py causing a circular import.
The library was installed via pip, and the issue persists after reinstalling.

Any clarification on whether this is a bug, an API change, or a version-related issue would be appreciated.
