Run your own mail server with your domain
name@yourdomain.com on your own server: Mailcow installs in one click, DNS records are written to Cloudflare automatically, webmail ready.
Captanel installs open-source Mailcow in one click, with mailboxes, webmail and a spam filter ready.
Deliverability
The DNS records your mail needs to avoid spam folders (MX, SPF, DKIM, DMARC) are written automatically if your domain is on Cloudflare. On Hetzner servers reverse DNS is set too.
Good to know
A server with plenty of memory is recommended; below 6 GB Captanel installs with virus scanning turned off. Some providers keep the outgoing mail port (25) closed on new accounts; ask yours to open it before setup.
