thanks for the message and for the huge, sensitive work that goes behind this.
This problem was not ICANN's making nor ICANN's choice yet of course demands from ICANN a response that is not easy at all. The changes you are implementing are very sensitive.
It is important for the community to note and comment on all changes and indications of trouble they/we notice as they may signal needs to adjust the changes you are describing, or to attend to specific users' issues. Everybody should be aware that this is very finicky and that the best responses to trouble are objective, civil reports with well documented information such as platform (hardware, operating system, email client or browser, etc.), full email headers, and copies of the system messages received.
Wishing everybody good luck!

ICANN IT Operations can indeed implement the DMARC “fix ups" for our mailman system.
We were waiting to test a vendor provided backport (changes from a newer version) patch for our mailman system.
We have completed testing as of this morning and plan schedule the change for this weekend.
The change will be almost transparent with exception to senders from domains with strict reject DMARC policies.
In this case, the “from:” will be replaced with the list address and we will insert a “reply-to:” header with the senders address.
Our testing indicates this is working flawlessly with the vendor patch.
The lac-discuss-en at atlarge-lists.icann.org and lac-discuss-es at atlarge-lists.icann.org cannot have this “fix up” enabled until the translation email parser is modified to look at the "reply-to” header when a DMARC sender “fix-up” is applied. The code change may take a few more weeks.
