We (postgresql.org) are similar to the FreeBSD folks in that we don't modify the body or the Subject line, so as to avoid breaking DKIM. Further, emails which over-sign the List-* headers are moderated and rejected when they hit our lists and we tell people to go fix their configuration. > I don't know how many exims (providers) uses that default, but our > job's email provider do that. When i complained, i got response, that > it is right and i do not understand DKIM... :-D It's certainly unfortunate that there are some folks who insist on using exim's default (which is also the recommendation from some RFC which is very annoying). We've been able to have some success getting people to fix things as, otherwise, they can't post to the PG mailing lists. Not sure if that would be helpful to mention to your provider but who knows, maybe it would be.. Thanks, Stephen
