[imp] "server does not support 8-bit message data" error

[Lorna Slawski]

Dear all,

since a few weeks we have been oberserving a strange behaviour when  
messages with a Content-Transfer-Encoding of 8bit are converted by  
Horde to be attachments. Someone sent an email with this encoding and  
without any attachments to me using Thunderbird 31.3.0. When I tried  
to forward this message via Horde Groupware Webmail Edition 5.2.4 with  
the option "As Attachment" or as "Attachment and Body Text" I received  
the error "server does not support 8-bit message data" and the email  
was not forwarded. Using the option "In Body Text" did not cause any  
error neither did a reply. We have experienced the same behaviour on  
different browsers and operating systems.
The sender of the email uses the same (Exim4-) SMTP server as I do and  
the email can be forwarded and answered perfectly using Thunderbird.

Horde log with level "INFO" does not seem to show anything concerning this.

Has anybody else experienced this problem? Any help is appreciated.

Have a nice evening!

Best,
Lorna
