Overview
Running your own mail server means full control of your data and unlimited mailboxes at flat cost — but deliverability is unforgiving. BetaZen Infotech sets up production-grade email servers using Postfix and Dovecot or the Mailcow suite, with Rspamd spam filtering, fat-fingered-typo-proof DNS (MX, SPF, DKIM, DMARC, PTR), TLS via Let’s Encrypt, webmail, and fail-safe backups. We warm up your IP, register feedback loops, and test against Gmail, Outlook, and Yahoo before calling the job done.
BetaZen Infotech deploys self-hosted mail for privacy-conscious firms in Kolkata, institutions across West Bengal, and companies elsewhere in India and overseas that have outgrown per-mailbox pricing.

Technologies we use
Why choose BetaZen
Unlimited mailboxes, flat cost
Fifty staff or five hundred — the server bill stays the same, unlike per-user SaaS mail pricing.
Your data on your server
Mail never leaves infrastructure you control, which matters for legal, healthcare, and finance workloads.
Deliverability proven, not assumed
We verify inbox placement at major providers and hand over the test evidence with the documentation.
How we work
Audit & Requirements
We review your domains, user count, compliance needs, and current mail flow, then choose the right stack and hosting location.
Server Build & DNS
The mail stack is installed and hardened, and MX, SPF, DKIM, DMARC, and PTR records are configured and propagation-checked.
Migration & Warm-up
Existing mailboxes are migrated over IMAP, and sending volume is ramped gradually so your new IP earns a clean reputation.
Verify & Handover
We run inbox-placement tests against major providers, tune filters, and hand over admin credentials with full documentation.
Frequently asked questions
Will my self-hosted email land in spam?
Not if it is set up correctly. Deliverability failures almost always trace to missing PTR records, unsigned DKIM, or cold IPs — all of which our setup and warm-up process addresses, with placement tests to prove it before handover.
Is self-hosting cheaper than Google Workspace or Zoho?
Above roughly 20–30 mailboxes, usually yes — one VPS bill replaces per-user subscriptions. Below that, hosted suites are often better value, and we will tell you so honestly during the audit.
Can you host our mail server in an Indian datacentre near Kolkata?
Yes — for organisations in West Bengal that need data kept in India, we deploy on Indian datacentres and can arrange on-premise installation in your Kolkata office, with our local engineers handling physical setup.
