Hi, Since th 19/20 february, I think, I got problem with my signature. It's a signature file with reference to an image.

When I send mai lto a client (old mail worked fine) I got this message from their server :

  1. 554-5.6.0 Corrupt message content 554 5.6.0 STOREDRV.Deliver.Exception:ConversionFailedException.MimeException; Failed to process message due to a permanent exception with message Le contenu du message a t endommag. MimeException: Erreur de contenu MIME : Nombre magique incorrect dans la pice jointe MIME Apple. ##

When I sent it to my colleague the image is not showing in place there's this text : "<Mail Attachment.as>" He use Mail (OSX) and he got Mail Attachment.as which id the png. And before the 19th feb i was seeing the image in the signature.

Thanks,

Problem with multipart/appledouble it seems. Until last thursday Thunderbird never encode with appledouble. Try to modify mimeTypes.rdf ti no avail. When I open "as new" a mail sent with wrong multipart and send it the new verson got a regular encoding and mime type.... What the F.....

To be more precise the problem is with the signature file (created with the thunderbird html editor as explained in the doc). If I include a image inline in the mail but remove the one on the signature the encoding is ok....

And to be more precise I got the problem only with PNG. Gif and jpeg are working as intended normal multipart not appledouble....
