header check logging truncating?

[postfix]

Im using milter_header_checks and i noticed in the logs it looks like 
part of the examined text (header in this case) is being truncated. It 
this intentional? Any setting to adjust how much it truncates? In the 
log below you can see after "(p=none di" it looks like it was cut off.
