# Do I need my own mail server?

**NO**—please, no

> Running Postfix in production means owning IP reputation, blocklists, TLS, key rotation, feedback loops, and 3 a.m. deliverability archaeology—to rebuild a commodity. Keep SMTP, drop the server.

Self-hosting outbound email is one of those projects that looks like a weekend of Postfix configuration and turns out to be a permanent part-time job. The protocol is 40 years old and beautifully open; the *trust infrastructure* built on top of it is where your weekend goes to die.

## What you're actually signing up for

- **A cold IP with no history.** Your fresh VPS address has zero reputation (or worse—check what the previous tenant did with it). You'll be [warming it](https://doineed.email/domain-warmup) from nothing, and low-volume senders can barely sustain a warm IP at all.
- **The checklist that never ends.** Reverse DNS. TLS configuration. [SPF](https://doineed.email/spf), [DKIM](https://doineed.email/dkim) signing and key management, [DMARC](https://doineed.email/dmarc). Bounce processing. Feedback loop registration with each provider. Rate limiting and greylisting handling per destination. Blocklist monitoring, and the delisting rituals when you land on one anyway.
- **Opaque failure modes.** When Gmail starts deferring your mail, there's no support ticket to file. You get a cryptic SMTP response and a long night of deliverability archaeology. Providers publish postmaster guidelines, not explanations.
- **Zero economies of scale.** Sending platforms run high-reputation pools, monitor them constantly, and remove bad actors—work amortized across thousands of senders. Alone, you do all of it for an audience of you.

## The part worth keeping

Here's the nuance: **SMTP the protocol is great.** It's the provider-agnostic standard that lets Laravel, Rails, Django, Supabase, or a 20-year-old ERP send mail without caring who's behind the socket. You can keep that portability—point your framework's SMTP settings at a provider (with Resend: `smtp.resend.com`, your API key as the password) and you've kept the interface while outsourcing the reputation management.

## The actual exceptions

Hard data-locality or air-gap requirements, or you're literally building an email provider. Both are real; neither is asking this website. For everyone else, your product deserves the engineering hours more than your MTA does.
