Hi, I've seen a clear bug when trying to send a ticket to a customer with an attachment made of a saved email itself. The MIME package complains with: Can't have encoding base64 for message type message/rfc822! at ../..//Kernel/System/Email.pm line 271 That is a bit weird. I've worked around the problem by forcing 8bit encoding for such attachments: --- Kernel/System/Email.pm.orig Fri Mar 17 16:23:53 2006 +++ Kernel/System/Email.pm Fri Mar 17 16:24:57 2006 @@ -268,6 +268,9 @@ # content encode $Self->{EncodeObject}->EncodeOutput(\$Upload{Content}); # attach file to email + if ($Upload{Content} =~ m/message\/rfc822/) { + $Upload{Encoding} = '8bit'; + } $Entity->attach( Filename => $Upload{Filename}, Data => $Upload{Content}, Now this is probably not the best fix but it actually works here. I would have liked to file this in bugzilla, but it doesn't seem to want to send me my initial password. Any ideas? A.
