Hi @externa1 ,

it seems your uploads got lost somewhere along the lines.

Since a few days I see the same file “unknown_transfer_encoding.bin”, created by a Fujitsu Q902 NAS. This behavior started after upgrading the NAS box to current firmware. The file contains html code but misses the html header and footer. So I assume this is a bug in NAS firmware. Question is why Kopano 8.4.5.0-33.1 stores this file with an .bin extension?

What is the source of your mail?

Martin

My QNAP NAS TS453mini creates the same emails with attached file “unknown_transfer_encoding.bin” since one of the last firmware updates. Kopano Version 8.4.90.1427

Martin,

I forget to mention, Fujitsu NAS is a re-branded QNAP NAS.

As temporary fix, I set the mail to plain text.

Martin

Good idea, i also switched to plain text ;-)

Could you provide a sample email? I would expect neither mime-type or filename is being set.

Unfortunately you can only see the problem in the RFC2822 mail. If you have “imap”-feature enabled for the user, then you should be able to use the download EML feature in WebApp to get the original received email.

Sorry I can’t upload the eml file - not enough privileges error.
So here the eml file as code:

That seems, unfortunately, to be the generated email and not the original one. :/ so not much to see.

Hello *,

I just ran into the same problem with new QNAP nas drives.

From my mails…

Subject: =?utf-8?B?W2dlZWxzZS1uYXMxXSBUZXN0bWVsZHVuZw==?=
MIME-Version: 1.0
Content-type:text/html;charset=utf-8

Does this help?

Blame QNAP. https://github.com/kisli/vmime/issues/173 . If you are not using the kopano.io builds, it comes down to your distribution if and when they update vmime.
