Subject tagging
Groups may wel use a tag in their subjects, like [tag]
. This might be added in the -group-
tool.
Adding tags before DKIM signing is extremely useful, as has been experienced before. By adding a tag before a mail server does it, the DKIM signature remains protected. The logic is simple: scan the Subject:
to already hold some [tag]
and if not, prefix it with that text and a space. Is there a use-case for multiple tags?
An attribute might be created, like t=[tag]
, in the group description. This attribute would be applied to all members described afterwards. Note however, that this could cause differences between backends, so the only supported use would be to tag all members with the same attribute value(s). An alternative would be to just use the group name as a [group]
tag.
This would be a first plugin to start parsing and modifying headers; that is something we will need to do at some point.
