“非发件人”IMAP搜索无法正常处理的电子邮件outlook.com

Question

这是我用IMAP做的一个测试outlook.com通过OAuth2连接

# THIS IS CORRECT
ipdb> mail.criterion = '(FROM "ship-confirm@amazon.com")'
ipdb> mail.get_headers()
[('"Inbox"', [<mailengine.scrubber.IMAPScrubber object at 0x110c21650>, <mailengine.scrubber.IMAPScrubber object at 0x110c21290>, <mailengine.scrubber.IMAPScrubber object at 0x110c1f6d0>, <mailengine.scrubber.IMAPScrubber object at 0x110c1f950>, <mailengine.scrubber.IMAPScrubber object at 0x110c1f750>])]

 # THIS IS INCORRECT (we should have 3 emails)
ipdb> mail.criterion = '(NOT FROM "ship-confirm@amazon.com")'
ipdb> mail.get_headers()
[]

# TEST (correctly getting all emails)
ipdb> mail.criterion = '(NOT FROM "anyword")'
ipdb> mail.get_headers()
[('"Inbox"', [<mailengine.scrubber.IMAPScrubber object at 0x110c21290>, <mailengine.scrubber.IMAPScrubber object at 0x110c1f950>, <mailengine.scrubber.IMAPScrubber object at 0x110c1f850>, <mailengine.scrubber.IMAPScrubber object at 0x110c1f690>, <mailengine.scrubber.IMAPScrubber object at 0x110c1f6d0>, <mailengine.scrubber.IMAPScrubber object at 0x110c1f750>, <mailengine.scrubber.IMAPScrubber object at 0x110c1f810>, <mailengine.scrubber.IMAPScrubber object at 0x110c1f1d0>])]

# TEST (incorrectly getting 0 emails)
ipdb> mail.criterion = '(NOT FROM "anyword@gmail.com")'
ipdb> mail.get_headers()
[]

我的猜测是@符号破坏了NOT FROM搜索。也许我该逃避一下？可怕的虫子？在
