The IMAP message_id in some messages has a nonzero strlen (e.g., 62) but the text is not visible if I echo it, and var_dump says it's an empty string. If I use ord and chr to duplicate the string character by character it looks like a legit message_id but the reconstructed string is still not visible if I echo it, and var_dump still says it's an empty string. Has anyone else encountered this? It's like a ghost message_id. It's there but it's not there and I can't do anything with it.
