Private email for organizations that need control over their communication

Your mailboxes are operated on sovereign infrastructure, protected by spam filtering, encrypted storage, monitoring, and backup.

The Problem

Many organizations don't control their own email

Free or bundled email platforms come with unclear data location, vendor lock-in, and limited operational visibility. Accounts can be suspended without warning. Nobody at the provider can explain exactly where your data sits or who can access it.

What weserberg.net Provides

Email operated on infrastructure you can actually verify

Private domain email operated on sovereign infrastructure, with encrypted storage, spam protection, monitoring, backup, and failover.

Custom Domain Email

Professional addresses on your own domain, with full webmail and IMAP/SMTP for any client.

Spam & Virus Protection

Multi-layer filtering catches spam, malware, and phishing before it reaches your inbox.

Encrypted Storage

Mail is encrypted on disk. All connections use TLS. No unencrypted data anywhere in the stack.

Shared Inboxes & Aliases

info@, contact@, donations@, shared addresses that route to the right people automatically.

Daily Backups

Automatic encrypted backups every night, with a defined retention period.

Mail Merge & Templates

Branded HTML templates and mail merge from Excel/Word recipient tables, for newsletters and donor reports.

How It's Operated Securely

The technical stack behind it

Postfix, Dovecot, Rspamd, and ClamAV run inside your own isolated environment. DKIM, SPF, and DMARC are fully configured and enforced, so nobody can spoof your domain.

Mail transport runs on Postfix with Dovecot for IMAP, Rspamd for spam scoring, and ClamAV for attachment scanning. DKIM, SPF, and DMARC are enforced (moving to p=reject after the first clean weeks). All connections use TLS 1.3. Servers run in a primary + hot-standby configuration with WireGuard-encrypted replication between nodes, monitored continuously with alerts routed to a person.

Good Fit If…

You want to move off Gmail or Microsoft 365, need a small number of shared inboxes, or want donor mail merge without a third-party marketing platform.

Not a Good Fit If…

You need thousands of mailboxes across many countries with in-house IT staff already managing it, that's usually better served by our Custom Infrastructure package.
