I can enable the "Replace the From: header address" in the mailman config to "Munge From" like in the above example, but it will mean that From: will be altered (see the explanation).
The way I understand the option to replace the From: header is that it will only happen for those that have a reject policy, for everybody else nothing changes. So if the mailinglist is supposed to stay useful for those with a reject policy the only option is to rewrite the from header for them.
Rewriting seems like the best option really, I doubt there is much chance of me managing to get the IS guys to change cirrus.com's DMARC policy and I guess we might not be the only people who cause trouble on this front.
ti.com also had issues caused by DMARC policy. We have extensively nagged our IT department over this and it got resolved? Probably. Not sure, but I have not been unsubscribed lately from lists and no complaints on people not receiving my mails... it could be that they do not indeed receive the mails which makes them happy ;)
Its not that you get unsubscribed, but everybody else who is rejecting your mails ;)
_dmarc.ti.com. 3600 IN TXT "v=DMARC1;p=quarantine;sp=none;rua=mailto:dmarc-aggr@ti.com;ruf=mailto:dmarc-for@ti.com;fo=0"
The p=quarantine means that your messages forwarded by the ALSA mailinglist will probably go to spam for people using gmail.
Some other mailinglists btw don't have this problem, since they forward the signed content of the mail unmodified. But since alsa modifies the subject as well as adding the info footer the original signature is no longer valid.
I added a filter for the gmail DMARC bounces (so mailman will not receive them) and increased the unsubscribe threshold now. But as you noted, it does not resolve the issue with the undelivered e-mails from the mailing list because the DMARC policy is too strong on the sender's side.
I can remove the subject prefix and footer but are you all ok with this? I only hope that mailman will not do other things with message body to break the signature. It seems that LKML also does not alter the message contents.
