migrate.py should fix known errors in the classic mail parsing #160

Open sebbASF opened 2 years ago

sebbASF commented 2 years ago

The migrate.py script should fix various known errors in the classic email parsing algorithm. For example:

remove line-wraps and other optional white space from header fields, especially Message-Id and References
fix up mbox date values that don't agree with the epoch

In the case of message-ids, line-feeds need to be dropped, and then any leading white-space removed. White-space within message-ids is not optional. To be determined if trailing white-space needs to be kept or trimmed.
