Cohousing-L Mailing List: listserve management

[Muriel Kranowski (murielk]

Our community listserv runs on Mailman, hosted for many years now by 
a local non-profit organization. (It didn't start out on Mailman but 
transitioned to it some years ago.)

All of a sudden some community members who use yahoo, aol, and other 
non-gmail email are having problems staying connected to the 
listserv, because those email services have adopted an anti-phishing 
protocol called DMARC and are applying the protocol so broadly that 
their email users can't post to a Mailman-type listserv. It's a mess! 
The non-profit host told me they don't have the resources to deal 
with this problem and suggested we find a different solution for our listserv.

I'm the list-admin, and I'm techie enough to understand the problem 
but not quite techie enough to figure out what to do next. I'd like 
to bring some options to our Electronic Communications subcommittee. 
Any ideas out there?

I've researched GroupServer and Sympa, and my eyes started to glaze 
over as I got into the details, so I decided to ask here, in case 
other communities also use Mailman and are facing the same problem.

I should add that I really like the functionality and convenience of 
an automated mailing list, and a number of our members are strongly 
anti-Facebook which has been suggested as an alternative to a 
listserv. I don't know if you need to have a yahoo or google email 
account in order to use their mailing lists or what their pros and cons are.
