[HCoop-Help] Email delivery not working

[Noufal Ibrahim]

Hi everyone,
    I've used mail.hcoop.net to send my email from my local machine for a 
long time now. Suddenly, however, I noticed my local mail queue freezing 
the messages. I see this in the logs

> 2023-01-29 15:59:35 1pM4uC-00068a-KH H=mail.hcoop.net

   Has something changed which I'm not aware of? How do I fix this?

Thanks.
