Email for your domain

Kotisivukamu can handle email for your domain in two ways. The choice is made in the dashboard under Domains → (select domain) → Email.

Option 1: Kotisivukamu​

Kotisivukamu offers two services:

  1. Incoming mail forwarding. All mail sent to @yourcompany.com addresses is forwarded to an existing mailbox you specify (e.g. firstname.lastname@gmail.com).
  2. Outgoing SMTP server. You can send messages from an @yourcompany.com address through Gmail or Outlook, for example, so the recipient sees the correct sender.
Kotisivukamu does not provide mailboxes

We do not store email. You need a "real" email service (e.g. Gmail) that messages are forwarded to and that you send from.

When you choose "Kotisivukamu", we automatically add the following DNS records:

TypeNamePurpose
MX@Receives incoming mail on our server
TXT@SPF record (allows Amazon SES to send on your behalf)
TXT_dmarcDMARC policy
CNAME*._domainkeyDKIM keys for signing outgoing mail

Adding a forward​

  1. Domains → Email → Add forward.
  2. Enter the source address (e.g. info, or * for all addresses) and the destination address(es).
  3. Save. The forward is active as soon as the DNS records have propagated (usually minutes).

Gmail: send messages from your @yourcompany.com address​

This is the most common setup: you use Gmail for daily reading, but want to send messages from your business address.

1. Create an SMTP account in the dashboard​

  1. Domains → Email → Create SMTP account.
  2. Save the username and password immediately — the password is not shown again. The server is mail.kotisivukamu.fi, port 587 (STARTTLS).

2. Add the address to Gmail​

  1. Open Gmail settings → Accounts and Import → Send mail as → Add another email address.
  2. Enter:
    • Name: the name you want recipients to see
    • Email address: e.g. info@yourcompany.com
    • Treat as an alias: untick if you want replies to come to Gmail while the "From" field shows correctly.
  3. Next Step. Gmail asks for the SMTP settings:
    • SMTP Server: mail.kotisivukamu.fi
    • Port: 587
    • Username: the username you got from Kotisivukamu
    • Password: the password you got from Kotisivukamu
    • Secured connection using TLS: selected
  4. Gmail sends a verification code to info@yourcompany.com. Because you have set up forwarding in Kotisivukamu, the code arrives in your Gmail — copy it and confirm.

Done. When composing a new message, you can choose the sender address in the From field.

Other email services​

  • Outlook.com / Microsoft 365: Settings → Mail → Sync email → Connected accounts → new POP/SMTP account.
  • Apple Mail (macOS/iOS): Mail → Preferences → Accounts → new Other Mail Account, use the same SMTP settings.
  • Mozilla Thunderbird: Account Settings → Outgoing Server (SMTP) → Add.

The settings are the same everywhere: server mail.kotisivukamu.fi, port 587, STARTTLS.

Forwarding as a webhook​

Email can also be forwarded to your own service as an HTTP POST request. This is handy if, for example, you want a customer's message to open directly in your ticketing system or CRM without a mailbox in between.

  1. Create a forward with these fields: Address (e.g. support) and Webhook address (e.g. https://yourservice.com/incoming-email). Leave the destination addresses empty if you want only the webhook, or fill in both so the message is both forwarded and POSTed.
  2. Save. When a message arrives, we parse the MIME body and send a JSON request to your webhook in the following format:
{
  "from": "sender@example.com",
  "to": ["support@yourcompany.com"],
  "to_local": "support@yourcompany.com",
  "subject": "Order status",
  "messageId": "<abc@mail.example.com>",
  "date": "Mon, 20 Apr 2026 19:00:00 +0000",
  "headers": { "...": "all headers" },
  "body": { "text": "Plain text...", "html": "<p>HTML...</p>" },
  "attachments": [
    { "filename": "attachment.pdf", "contentType": "application/pdf", "size": 12345, "content": "base64..." }
  ],
  "authentication": { "spf": {...}, "dkim": {...}, "dmarc": {...} }
}

Your server must respond with a 2xx status code within 20 seconds. Otherwise we retry up to three times with increasing delays; 4xx responses are not retried (our interpretation: a configuration error, not a temporary fault).

Tip

Use an HTTPS address only. Attachments arrive base64-encoded inside the JSON body, so you can handle everything with a single parse.

Limits​

  • Incoming forwards: up to 50 per domain.
  • Maximum message size: 50 MB (headers + body + attachments combined). Larger messages are rejected at the SMTP level before forwarding.
  • Outgoing messages: 200 messages per day per SMTP account (higher limits on request).

Option 2: Another provider​

If you use Google Workspace, Microsoft 365, or another commercial email service, Kotisivukamu does not add email-related DNS records automatically. Here is what to do:

  1. Sign up for the service of your choice using your domain.
  2. The service gives you a list of DNS records (MX, SPF, usually also DKIM).
  3. Add the records in the dashboard's DNS settings card and save.
  4. The service verifies the records — this usually takes a few minutes.
Need help?

Setting up Google Workspace or Microsoft 365 requires several DNS records at once. If you like, we can add them for you — contact customer support.
