[jetty-users] I'm not subscribed, I can't unsubscribe.

[Someone <jetty-client@xxxxxxxxxxxxxx>]

Since April this year I'm suddenly getting messages from this list. I was unsubscribed successfully way back on Jan 4 2022. I've now tried to unsubscribe myself in two ways:
- sending email to jetty-users-request@xxxxxxxxxxx, but It gets an email bounce, because jetty-users-requests is not a valid email address at that domain.
- going to https://www.eclipse.org/mailman/listinfo/jetty-users. But I can't unsubscribe there, because I don't have an account, as is confirmed by the website when I try to do a password reset for the email address that this mailing lists sends me messages at.

So please let me know how I can stop the email from jetty-users,

Thanks
