When building statistics from mail servers, messages which where processed by Sender Rewriting Scheme (SRS) are mis-classified as internal mail while they are external, and appear to come from a huge number of different addresses which in fact correspond to the same actual sender.
Add a rewriting function that process such addresses and extract the relevant information from it.
With this change, the addresses SRS0=HHH=TT=example.org=alice@example.com and SRS1=HHH=example.com==HHH=TT=example.org=alice@example.net are converted to alice@example.org, the actual sender.
