Custom SMTP
By default, emails xTool sends (invoice emails) come from noreply@xtool.invoice-portal.de. Custom SMTP lets the organisation send them through your mail server, with your From address.
This is outgoing mail only. Inbound invoices use Interfaces → Mailbox Configuration. See Receive by email.
The wording of the invoice email is Email templates, not SMTP.
Open Custom SMTP
- Sign in and select the organisation.
- Open Channels → Email.
- Open Custom SMTP.
Without a configuration, the page notes that mail is sent from the default no-reply address.
Configure
Fill SMTP Settings and click Save Configuration (or Update Configuration when editing).
| Field | Required | Description |
|---|---|---|
| SMTP Host | Yes | Mail server hostname |
| Port | Yes | 1–65535 (often 587 for STARTTLS, 465 for SSL) |
| Security | Yes | None, TLS (STARTTLS), or SSL/TLS |
| Requires authentication | No | Turn on if the server needs a login |
| Username / Password | If auth is on | On update, leave password empty to keep the current one |
| Sender Address (From) | No | From address. If empty, xTool uses the SMTP username |
| BCC Address | No | One blind-copy address on every outgoing document email |
Use a single address in From and BCC (not a comma-separated list).
Test and disable
Test Connection checks that xTool can log in to the server.
To stop using your server, Delete the configuration (confirm). Outbound mail returns to the default sender.
If an email template has its own BCC, that value is used; otherwise a Custom SMTP BCC may still apply. See Email templates.
Send a document
After SMTP is saved, send by email as usual. Recipients see your From address when you set Sender Address.
