In the course of replacing an old Python 2.7 email filter tool with a rewritten Python3 version, I stumbled across a ugly case, where such an header: X-Microsoft-Exchange-Diagnostics: =?utf-8?B?MTtCTDJQUjAyTUI1MTQ7MjM6bEtRRlNaUHQvVTk5WCttdktlOUVrUGQvVFBH?= =?utf-8?B?cDFJemVUeXFzOGNzYnZOYWlwMDZpR0YzbXZyY09WaTBKM2pkeUl4S1VDMkxw?= =?utf-8?B?eVRkNWthRW9waUhJTzczTWd5WDZOQ3hMNU1haGFvQTVzVTdRZmxJUnZlblpW?= ... is regenerated as: X-Microsoft-Exchange-Diagnostics: 1;BL2PR02MB514;23:lKQFSZPt/U99X+mvKe9EkPd/TPG p1IzeTyqs8csbvNaip06iGF3mvrcOVi0J3jdyIxKUC2Lp yTd5kaEopiHIO73MgyX6NCxL5MahaoA5sU7QflIRvenZV which is plain wrong of course. I'm using email.message_from_binary_file for parsing and BytesGenerator.flatten for regeneration. Since those are LKML public mails, I'm attaching both versions. I'm using 3.4.4, but also the email module from current hg for testing. |

Hmm. There appear to be at least two bugs here, using the SMTP policy. I thought I had test cases like this, but clearly I don't :( |

Sorry guys for not providing this earlier. It turned out, that the sub optimal behaviour is related to a unfortunate policy choice: email.policy.SMTP. |
