hello please how can I protect my server from this option so that no one can access and send emails like that please I want to protect my server
what option ?
The good news is that Virtualmin will protect your server with the default settings that are applied to it when it is installed.
Since you use Cloudflare or a third party DNS, you need to be careful about copying over exactly the DNS records in Virtualminās DNS to Cloudflare (adjusting for its quirks) or other third party DNS server that you use.
In an earlier message in this thread I have identified a manual copy - paste error that you made with DNS records. Obviously such errors will cause issues with email delivery from your Virtualmin server to other servers on the internet.
You should consider doing away with Cloudflare and using Virtualminās DNS server for all the domains that you host.

my brother you told me that anyone can send emails from my server because it is not secure and that is what you did in the photo I asked how to protect my server against that
hi brother i said i donāt have cloudflare it was just a test but i removed it thanks for seeing the pictures
If you dont use cloudflare or any other third party DNS, then:
- Tell your domain registrar to apply glue records to your domain
- Then peruse this thread - I can't configure my email :( - #12 by calport
This will result in a secure Virtualmin server which cannot be abused by spammers and can send mail from your users without it being flagged as spam.
