Migrate · Any SMTP server

## From any SMTP server to Oveyon, _no surprises_.

If your application already speaks SMTP, the switch is host, port and credential. What changes is what comes with it: your own DKIM per domain, suppressions with compliance built in, an outcome per recipient and a record of everything.

01 · Three steps

### Get started in three steps.

#### 1. Connect the domain

Under Domains, add the domain and publish what the panel generates — the SPF include, the DKIM key and DMARC. Only a domain with verified DKIM sends from here, and the wizard checks live.

#### 2. Create the SMTP credential

Under Sending → Credentials. The password is generated by the server and shown only once, at creation; the credential can be restricted to domains of the account — a sender outside them is refused on the spot with 550 5.7.1.

#### 3. Swap host, port and credential

smtp.oveyon.com, port 587 with STARTTLS or 465 with implicit TLS; 2525 and 8025 as alternatives. Keep the old relay until you see the first deliveries under Messages — then turn it off there.

02 · What the old relay did not have

### What arrives with the host swap.

#### Suppressions with compliance built in

Bounced, complained, unsubscribed — the platform keeps them and honours them at send time; a complaint cannot be deleted.

#### An outcome per recipient

Delivered, bounced, blocked, with the reason in plain language; a signed webhook per event; a record readable for your plan’s window.

#### Policies at send time

Block a destination, allow only a list, force transactional — with a simulator that calls the same evaluation.

#### Inbound

Point your MX and every mailbox becomes a webhook, Telegram, Slack or forwarding — with a safety verdict on every message.

03 · On arrival

### What is different here.

#### Your own DKIM per domain

Each domain is born with its own key, generated here, and the wizard checks the DNS live on every visit. SPF, DKIM, DMARC, MTA-STS, TLS-RPT and ARF out of the box.

#### A complaint can never be deleted

Not from the panel, not through the API, not by deleting the domain and re-adding it. Your list leaves here whole, whenever you want.

#### A ramp that counts days you sent

A new domain climbs in steps of effective days — not calendar days. Rolling back does not reset what you really built.

#### A record ready for audit

Who did it, when, what changed — including when the “who” was our support. A trail without purge, visible under Account → History.
