I've encountered a problem parsing an email with this Subject: header: Subject: Be sure to redeem your =?utf-8?Q?$?=201.71 credit card reward certificate by the end of the year email._header_value_parser.get_unstructured defers to get_encoded_word, passing the argument '=?utf-8?Q?$?=201.71 credit card reward certificate by the end of the year' get_encoded_word eventually calls email._encoded_words.decode with the argument '=?utf-8?Q?$?=201.71 credit card reward certificate by the end of the year?=' This doesn't seem right, but I'm unsure of the syntactic priority of =XX and ?= in this case. The policy for this is email.policy.SMTP + email.policy.strict (not sure if that's ideal; I'm retrieving messages from mbox files and over IMAP). |

It's worth noting that dealing with this header eventually causes the header parser to enter an infinite loop. |

This problem does not exist in Python 3.6 or Python 3.8; it appears to only exist in Python 3.7. |

It turns out this was a problem in 3.7.4; Python 3.7.5 seems to have fixed this. Sorry for the noise. Guess it's time to update my application to use 3.7.5! |
