Fixing that is zero-maintenance with no negative side-effects.
The question here is how to distinguish headers which absence should be treated by ignorance (e.g. `Sender`) from headers which absence should be oversigned, e.g. `Subject` or `Reply-To`. In fact, I was asked about somehow similar issue in Rspamd that also performs DKIM signing. So far, I'm not quite sure if there is a simple solution for this problem. > <skipped> _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
