Apps / Mailcow
Managed Mailcow hosting.
One server, no app limits.
A complete self-hosted mail suite: Postfix, Dovecot, Rspamd, and SOGo webmail in one dockerized stack. Your domains, your mailboxes, your data, running behind the managed mail gateway.
What it is
Mailcow is the complete self-hosted mail suite: Postfix, Dovecot, Rspamd, and SOGo webmail in one dockerized stack. Your domains, your mailboxes, your data, with a real admin UI over all of it.
Minimum RAM
6 GB
Fits on SC-6GB; SC-16GB is the comfortable pick with room to stack.
What we install
The playbook deploys Mailcow dockerized per the official documentation, DNS records (MX, SPF, DKIM, DMARC, PTR) prepared with you, TLS issued, and the stack placed behind the managed network so port 25 life starts on the right foot.
What managed covers
Stack and server updates with snapshots first; daily snapshots plus dual offsite backups of every mailbox; monitoring on queues and services; the managed firewall; and a team whose actual specialty is mail infrastructure.
The app is $0. The managed server is the only bill, and everything above is part of it.
What does managed Mailcow hosting include?
The whole suite deployed correctly, DNS done properly the first time, mailboxes backed up twice offsite, and monitoring on the queues. Mail is the most operations-heavy thing you can self-host, and this is a host whose differentiator is mail operations.
Why self-host email at all?
Unlimited mailboxes at flat cost, aliases and domains without per-seat pricing, and mail data under your jurisdiction. Per-mailbox SaaS pricing makes a twenty-inbox company pay forever for what one server does; Mailcow makes mailboxes free to mint.
Is self-hosted mail deliverability hopeless?
Not on infrastructure built for it. Deliverability lives and dies on IP reputation, correct DNS, and authentication, which is precisely the stack we run for a living: SPF, DKIM, DMARC, and rDNS set up as part of the install, on network space we keep clean. Test it yourself with our deliverability tester afterward.
How big a server does Mailcow need?
6 GB of RAM is the official requirement and the catalog respects it: the suite runs a dozen services. SC-8GB is the natural home, with room left for an Uptime Kuma watching it.
Stack it

Frequently asked questions
How much RAM does Mailcow need?
6 GB minimum per the Mailcow documentation, and the resource meter enforces it. Large mailbox counts or heavy filtering move you toward 16 GB.
Are mailboxes backed up?
Daily, twice offsite, the full stack: mailboxes, settings, and DKIM keys. A deleted mailbox is a restore, not a funeral.
Will you help with DNS?
Yes, all of it: MX, SPF, DKIM, DMARC, and reverse DNS are set with you at install, then verified with a real send through our own testing tools.
