I'm adding address book users into the user_prefs files, but without
the signing domain this is useless and emails for my users are still
getting tagged up as spam (these in particular score 7-10 points
without the whitelist). Is there a better way, or do I just have to
go in and find a DKIM-Signature for each address book entry and then
parse out the d= field?
Yes, you need the d= part. Note You should only do this for messages
from domains that are signed and pass DKIM with DKIM_VERIFIED. Adding
whitelist_From_dkim won't do any good if you don't have DKIM_SIGNED
and DKIM_VERIFIED.
grep -r "^DKIM-Signature:" $HOME/Maildir | awk '{print $4}' | sed 's/d=//'
| sed 's/;//' | sort -u
I dunno, doesn't seem that efficient (oh, and it doesn't work since the d=
doesn't appear in the same location in all the headers).
If you are going to use sed, You need the entire DKIM_Signature header
as one line. Use formail to extract the header, for example
formail -c -x DKIM-Signature:
NAME
formail - mail (re)formatter
...
-c Concatenate continued fields in the header. Might be convenient
when postprocessing mail with standard (line oriented) text utili-
ties.
