1. Overview
2. Hostname
The server address for all INGOS E-Mail V2 customers is:
mail.ingos.net
Exceptions apply to customers using a dedicated Enterprise server, where custom settings may be applicable.
Use only mail.ingos.net (for Basic and Pro subscriptions) as the hostname for configuring your email services. Other hostnames are not supported and may result in connection issues.
3. Port Overview and Usage
The following ports are used for accessing INGOS E-Mail. All connections are encrypted,
and unencrypted ports (e.g., Port 110 and 143) are not supported.
| Function | Port | Protocol | Usage |
|---|---|---|---|
| Web Interface and ActiveSync | 443 | HTTPS | Access to the web interface and synchronization of mobile devices via ActiveSync. |
| SMTP (Sending) | 465 | SSL/TLS SMTP | Sending emails over an encrypted connection. |
| SMTP (Alternative) | 587 | Submission | Alternative to Port 465 for email sending, also encrypted. |
| POP3 (Receiving) | 995 | SSL/TLS POP | Receiving emails via POP3 over an encrypted connection. |
| IMAP (Receiving) | 993 | SSL/TLS IMAP | Receiving and syncing emails via IMAP over an encrypted connection. |
| Chat (XMPP) | 5222 | XMPP | Access to the chat feature (if enabled). |
Port 80 is used for HTTP requests but is automatically redirected to HTTPS (Port 443) for secure connections.
Ports 110 (POP) and 143 (IMAP) are not supported as only encrypted connections are allowed.
4. What is a Dedicated Server?
A dedicated server means that a single customer uses a server exclusively for their emails and data. This is different from the Basic or Pro version, where multiple customers share a server.
A dedicated server offers numerous advantages:
- Higher Security: Since only your organization has access to the server, individual security measures such as Two-Factor Authentication (2FA) or Single Sign-On (SSO) can be implemented more easily. These adjustments provide additional protection.
- Better Reputation: Since only your emails are sent through the server's IP address, the IP remains clean and has a lower risk of being added to spam lists.
- Brand Identity (Branding): You can customize the user interface to match your brand, such as adding your logo or colors. This strengthens recognition among employees and customers.
- Flexibility: The server can be configured according to your requirements, such as specific ports or custom security policies.
- Higher Performance: All server resources are exclusively available to you, resulting in faster processing and more stable usage.
The Enterprise version of INGOS E-Mail is based on this dedicated server structure, making it ideal for businesses requiring maximum security, performance, and customizations.
5. Enterprise Customers
For customers using the Enterprise variant, ports can be customized according to their specific requirements and security policies.
The default configuration, however, aligns with the standard ports listed above. If individual changes are needed, please contact technical support.
6. Example: Connecting a Web Application to INGOS Email
The following configuration shows how to set up a web application to send and receive emails via INGOS Email. In this example, we use IMAPS for receiving and SMTPS for sending emails. These settings ensure secure and encrypted connections.
Settings for the Web Application (example):
| Parameter | Setting |
|---|---|
| IMAP Hostname | mail.ingos.net |
| IMAP Port | 993 |
| IMAP Username | example@ingos.com |
| IMAP Password | yourSe$curePasswordwithNumbers0612 |
| Leave emails on the server | Yes |
| IMAP Connection Type | TLS |
| Use the same mail server for sending | Yes |
| Email Header Encoding | base64 |
| SMTP Hostname | mail.ingos.net |
| SMTP Server Port | 25 |
| SMTP Port (TLS/SSL) | 465 |
| Use SMTP Authentication | Yes |
| SMTP Username | example@ingos.com |
| SMTP Password | yourSe$curePasswordwithNumbers0104 |
| SMTP Connection Type | TLS |
Explanation of the Settings
This configuration ensures that the web application can securely fetch incoming emails via an encrypted IMAPS connection (Port 993) and send outgoing emails using SMTPS (Port 465).
It is recommended to enable the setting "Leave emails on the server" to ensure that emails remain accessible on other devices.
With these settings, you can, for example, operate a contact form that automatically sends confirmation emails to users or saves incoming messages to your email inbox.
Do not use your personal email account in a web application or form. In case of an attack, there is a risk that your personal account could be compromised.
To minimize this risk, please use a separate email account specifically designated for use in web applications. Additionally, we strongly recommend using INGOS Web Space in combination with the INGOS Web Application Firewall (WAF) to ensure optimal protection for your applications.
