chatmeow69 Hello, I have an SSL/TLS certificate bug. I have several domain names for the mail server.mydomainname, admin.mydomainname and client.mydomainname, but Outlook tells me that my certificate is not valid.
ETNyx Got domain also on CloudFlare. All my records are in “DNS only” mode, everything works fine without moving certificates to CF, so my guess is, your DNS is not setup right, if your intend is to use “DNS only” mode as you wrote,…
esackbauer chatmeow69 Consult their documentation. the mailcow certificates are in /opt/mailcow-dockerized/data/assets/ssl Upload them to cloudflare as DocFraggle pointed out. You have to do this every 2 months whenever mailcow pulls new certificates from Lets Encrypt. Or you do it the other way around, then you need to copy the cloudflare certificates to mailcow: https://docs.mailcow.email/post_installation/firststeps-ssl/#how-to-use-your-own-certificate You need to do this also each time Cloudflare renews the certificates.
chatmeow69 Hello, I followed the documentation to use my own certificate but that did not solve my problem. ee.bin1kB
