Email Forwarding
When you want to receive emails sent to another email address, you can choose between setting up email forwarding or an alias.  
Forward vs Alias: What’s the Difference?
Email Forwarding: This feature redirects emails from one mailbox to any other email address, even outside your domain. For instance, emails sent to contact@example.com can be forwarded to example@gmail.com.
Email Alias: An alias allows you to use multiple alternative email addresses that deliver messages to the same mailbox within the same domain. For example, emails sent to contact@example.com, admin@example.com, and shop@example.com will all be delivered to the mailbox for yourname@example.com.
How to Set Up Email Forwarding?
To set up email forwarding, follow these steps:
Log in to your webmail account at https://mail.op-email.eu/SOGo/ 
Once logged in successfully, navigate to Preferences → Email → Forward.
Check the Forward incoming messages box.
Enter the email addresses to which you want the messages forwarded.
If needed, enable the Always forward option and check Keep a copy to retain a copy of the emails in your account.
Save the changes.
Important:
A valid DKIM record is mandatory for email forwarding on domains using our email service.
If DKIM is missing, receiving mail providers, especially Gmail may reject forwarded messages with errors such as “5.7.1 This message does not meet our delivery requirements.”
The DKIM record is automatically provided when purchasing a mailbox, or it can be retrieved via RCP → Email Accounts → Domains → DNS (under Actions for the domain).
After adding or updating the DKIM record, please allow time for DNS propagation. If emails are still not delivered to the inbox, we recommend checking the recipient’s spam folder.

Email Solution: Frequently Asked Questions
This article addresses the most common questions regarding our business email solution. For quick navigation, questions are grouped by topic.
Account Management
 
Why can’t I add a domain to the email solution?
You may see the error “Invalid owner handle!” when adding a domain.
- If the domain is registered with Openprovider, the handle you use when adding the domain must match the domain’s registrant handle. If they don’t match, the error appears.
- If the domain is with another provider, this rule does not apply. You can use any handle under your account.
 
“An unknown error has occurred” appears when creating an email account. Why?
This error happens because no domain has been added yet. At least one domain must be added before you can create an email with the domain.
Storage and Limits
 
How much storage is included per email account? Are there any restrictions?
Each email account includes 15GB of storage by default, which can be increased if needed.
- Additional storage is available in 5GB increments for $0.25 per month, based on your requirements.
- You can create multiple separate email accounts, each with 15GB storage (and independent upgrades). Each account is billed separately.

Features and Customization
 
What is Webmail?
Webmail is an online service that allows users to access and manage their email accounts through a web browser. With the availability of the Internet, webmail users can access their accounts from any device using any web browser. They can send, receive, and organize emails directly on a web interface without the need for external software. Gmail, Hotmail, Yahoo, and Outlook are some of the most modern webmail services on the market.
Security: Because webmail operates over the internet, security is essential. Webmail services use encryption to protect data during transmission and offer additional security features such as two-factor authentication (2FA) and spam filtering.
 
Can I access calendars outside of the webmail interface? (e.g., via CalDAV)
Yes, our email service supports CalDAV, which lets you connect your calendar to apps that support it.
 
Is it possible to customize the webmail interface?
The standard webmail interface cannot be customized. However, we do offer the option to provide a dedicated server where interface customization is possible.

Emails going to spam/junk folder - How to adjust your spam filter settings
If legitimate emails from external senders are being delivered to your spam or junk folder, this article explains how the spam filter works and how you can adjust your personal settings to prevent this.
Why does this happen?
Our mail platform automatically scores every incoming email based on a number of factors. If an email scores above a certain threshold it will be moved to your junk folder. Occasionally, legitimate emails from trusted senders may score slightly higher than expected due to shared sending infrastructure or email content, and end up in your junk folder unintentionally.
How to fix it
You have two options:
Option 1 - Whitelist a specific sender (recommended)
Log in to https://mail.op-email.eu with your email address and password
Click the Spam filter tab
In the Whitelist section, enter the sender's email address or domain (e.g. 
sender@example.com or 
*@example.com for an entire domain)
Click Add item
Whitelisted senders will never be classified as spam.
Option 2 - Adjust your spam filter thresholds
Log in to https://mail.op-email.eu with your email address and password
Click the Spam filter tab
Drag the first slider (green/yellow boundary) to the right - we recommend setting it to around 9
Drag the second slider (yellow/red boundary) to the right - we recommend setting it to around 14
Click Save changes
Tip: Using both options together gives the best result.
What do the score zones mean?

🟢 Green
