(no subject)

Can anyone recommend a solution for a discussion-type (not marketing) mailing list that is not on my own domain? Yahoo, which has been cranky and unreliable about accepting mail from eristic.net for a long time now but used to work enough of the time to be going on with, has apparently decided it doesn't want to anymore*, and I'm tired of getting bounce messages from the subscribers on the list whom I can't persuade to use different addresses and having to separately forward things to them from my Gmail address every time (because I do want them getting event announcements and being able to reply to RSVP). For what I hope are obvious reasons I do not want to use a Yahoo group, and Google groups, as I recall, are a big pain to be on with anything other than a Gmail address because you can't manage your own subscription. I don't know if there's anything else out there these days.

Alternatively, although I dread having to open a support ticket because A Small Orange's customer support has become crap (oh for the days of Drak.net), if anyone can positively diagnose some problem with the mail server configuration that could be causing this, that would be helpful information if I ever manage to work up the combination of stubbornness/patience/energy required to do so. (Fiddling with it directly is definitely beyond me in terms of knowledge, and maybe not even possible in a permission sense.)

* Common error response over the past few days has been delivery temporarily suspended: lost connection with mta7.am0.yahoodns.net[98.137.159.24] while sending RCPT TO but I have also received "message temporarily deferred due to user complaints" kinds of errors multiple times in recent months (which I assume are not due to literal persons filing literal complaints with Yahoo?).
