vbounce does not catch qmail bounces

[Alex Woick]

Just recently backscatter starts to hit me very bad, and I found out 
that bounces generated by qmail are not detected by the vbounce plugin. 
Here is such a backscatter mail:

Perhaps a phrase like "wasn't able to deliver your message" could be 
added to the detection. Or very qmail-specific:
/qmail-send program .{80,140}This is a permanent error/

Tschau
