Hello guys,
I have a question about delegation coding pattern(I'm working with Python

In order to describe my question , I'll provide particular example:
Let assume I have two classes written in module named person.py:
Case 1:
class Person:

smtplib.SMTPRecipientsRefused: {'aahlin!@gmail.com': (550, 'restricted

As in this question, the answer has reference to RFCs that spec it out, and
state that exclamations are ok, so why is smptplib throwint this error?
