Modern Email Stacks Are Resource Hungry
Don't Let "Standard" Software Slow Down Delivery
Standard email server software often lags under the load of modern requirements like real-time antivirus scanning, heavy spam filtering (RSPAMD), and database operations. This is why dedicated resources are vital.
-
●
Heavy RAM Usage: Antivirus engines like ClamAV can consume 1GB+ RAM alone just to stay resident in memory.
-
●
Disk I/O Latency: Traditional HDDs cannot keep up with thousands of concurrent small file writes (email logs and maildir storage).
-
●
CPU Spikes: Real-time SSL/TLS encryption and decryption for every single connection requires modern CPU instruction sets.

Frequently Asked Questions (FAQ)
For Docker stacks, does Xeon/Linux or EPYC/Linux work best? ▶
Both are excellent, but for Docker-heavy stacks like Mailcow, EPYC's high core count offers superior parallel processing for simultaneous antivirus and antispam scans.
Can I use cPanel/WHM on a dedicated email server? ▶
Yes. While cPanel is a general hosting panel, it includes a robust Exim-based mail system that is very easy for resellers to manage at scale.
Do you offer support for MTA and DKIM initial setup? ▶
We provide the "unmanaged" power. However, our technical specialists can assist with network-level configurations like rDNS which are required for DKIM and SPF to work correctly.
