I have a filter that is set to apply before sending messages. The result of the filter is stored in the Sent folder, but the message that actually goes out is the unfiltered one.

My filter consists of a couple of "Pipe Through" actions. The message stored in the Sent folder is exactly as I expect, so the filters seem to work correctly.

The same filter worked correctly In kmail 4.4.11.

Reproducible: Always

Steps to Reproduce:
1. Go to Configure Filters, create a filter that modifies a message
2. In the Advanced tab, check "Apply this filter before sending messages"
3. Compose and sent a message, e.g., to yourself
4. Verify in the Sent folder that the filter was applied
5. Wait for the message to be delivered and see that the filter was *not* applied

Actual Results:  
Sent folder shows the message with the filter applied.
Message that went out didn't have the filter applied.

Expected Results:  
Message that went out should (1) have the filter applied and (2) be identical to the message in the sent folder.
