Hi all,
I added psddmarc to the latest zdkimfilter.

After some thought, I chose to use and distribute a file like the one attached.  Two reasons for doing so are as follows:

1. Avoid to invent yet another file format, specifying header line, initial dot, comments, and the like.

2. Reuse the library calls already available for parsing and searching the PSL.

On the second call, the software passes the organizational domain resulting from the first call, and thus retrieves the "super organizational" domain, if any.  The file only contains the domain from psddmarc.org registry which actually sports a DMARC record.  While the experiment is ongoing, the file will have to be updated.

It would be convenient, if more implementations will find the above reasons convincing, if such a list would be maintained and distributed by psddmarc.org along with (or instead of) the csv format.  After all, since this list extends the PSL, keeping the same format may make some sense.


Best
Ale
