Checking for aol.com and yahoo.com here alone will not work. I have a bunch of other subscribers that have accounts with providers that are owned by Yahoo (mostly) and AOL, but whose addresses are not of this form. I would have to do this for all addresses, to be safe.
You only have to mung those addresses for which the domain publishes a DMARC p=reject policy. This almost certainly does not include aol and yahoo provided 'other' domains.
The code in Mailman 2.1.18+ actually does a DNS lookup of the DMARC policy. In all the myriad @python.org list posts, the only domains I see with p=reject are aol.com, yahoo.com and paypal.com.
If I do this and add the bit about the Reply-To, what would the code look like?
I'm currently between flights in an airport. When I get a chance, I'll post some code.
