Mailing list messages not received

Mailing list messages not received

I subscribed to two mailing lists on my zoho.com account, (SuperCollider users and SuperCollider developers, both for SC audio software). Everything was fine for a couple of weeks, but now I am not receiving messages from them. I never see them in my inbox, and I've looked for them in Spam as well, but nothing. It's like they don't exist.

But, I have another mail account elsewhere which (because of a technical problem) I couldn't unsubscribe. *That* address is receiving from the lists. So I am completely certain that the lists are up and running. I also tried resubscribing from zoho.com, but majordomo tells me I'm already subscribed.

I am at some loss to understand how all messages from a frequent sender could be lost entirely, without a trace.

Messages from my mom and from my students come through with no problem. Also, I'm sure it isn't about frequency of messages because I'm getting github notifications, no problem.

Something zoho doesn't like about the lists' domain, maybe? lists.bham.ac.uk

Thanks for advice.
