Hi, ok, just for clarification what would be a good solution for this: I've not mentioned that we need the content-transfer-encoding for the attachments of the mail.
Some ideas from my side: 1. use a parameter like contentType, let's say content-transfer-encoding: If this parameter is set ALL attachments will have this content-transfer-encoding. The problem I see here is that it's probably a bit misleading as the contentType parameter affects the mailbody and content-transfer-encoding the attachments. Maybe this issue could be solved by renaming the parameter to something like "attachment-transfer-encoding" 2. when an attachment will be added to the exchange object the contentType could be defined like this: In the org.apache.camel.component.mail.MailBinding class then we extract the content transfer encoding, for example: Maybe we discuss the possible solutions before I start patching. kind regards, Christoph -- View this message in context: http://camel.465427.n5.nabble.com/camel-mail-content-transfer-encoding-configurable-tp5752504p5752738.html Sent from the Camel - Users mailing list archive at Nabble.com.
