[issue32058] Faulty behaviour in email.utils.parseaddr if square brackets in subject

I do get this data from an IMAP fetch statement, see my code below:

rv, data = imap.fetch(num, "(BODY[HEADER.FIELDS (FROM SUBJECT)])")
if rv != 'OK':
logging.error("Error getting message sender and subject (" + 
num.decode("ascii") + ")")
return
logging.info("Got message " + num.decode("ascii"))

sender_subject = data[0][1].decode("utf-8")
sender = email.utils.parseaddr(sender_subject.replace('[', 
'').replace(']',''))[1].replace("\r\n", "")

Thank you for providing this new API though, I will make sure to switch to that.

[issue32058] Faulty behaviour in email.utils.parseaddr if square brackets in subject

[tom de wulf]

New submission from tom de wulf <dewulfm...@gmail.com>:

Probably a parsing bug in email.utils.parseaddr.

How to recreate:

>>> import email.utils
>>> test = 'Subject: I am a bug [Random]\r\nFrom: someone 
>>> <some@email.address>\r\n\r\n'
>>> email.utils.parseaddr(test)
('', 'I')
>>> email.utils.parseaddr(test.replace('[', '').replace(']',''))
('someone', 'some@email.address')

Expected behaviour: no need to remove the []'s
