Sending mails from your website
If you want to send emails from your website, we recommend you use the PHP mail() function, but you can also use the following settings:
- Outgoing server: mailout.one.com
- Port and encryption:
- 587 with STARTTLS (recommended)
- 465 with SSL/TLS
- 25 with STARTTLS or none - Authentication: your email address and password
Note: You can only use mailout.one.com to send emails, if your website is hosted on our servers.
