If not directly related to Zimbra might be worth posting this question in the Kopano forum: https://forum.kopano.io/category/25/syn ... via-z-push

Sorry for the silly question: did you forced the update to php8.1 or did it come from the yum repos ?

Thanks

Hello, I missed this webinar, anywhere where I can find the material ?

for DNSSEC I tried to configure dnsmasq (I use it for split DNS) but lookups fail with unreachable hosts if enabling dnssec
for DANE I found the Zimbra wiki and seems it can be enabled with 2 configuration settings ?
thanks

Excellent, many thanks for the full explanation and looking forward to the DANE webinar !

Hello, I made it work by having the wildcard certificate configured on both the reverse-proxy server (where the MTA_STS.txt is located) as well as on the Zimbra server. To achieve this I have created the letsencrypt wildcard certificate on the reverse proxy server using cerbot, I created the certifi...
