URL Safeguard
If configured accordingly, the URL Safeguard cross-checks the links in inbound emails against entries in the following lists:
- NoSpamProxy Allowlist, a list of known websites curated by NoSpamProxy.
- The local allowlist created by the administrator.
Domains that exist in one of these lists as well as your corporate domains will never be rewritten by the URL Safeguard.
NOTE: You can make settings for the NoSpamProxy Allowlist and the local allowlist under Configuration > URL Safeguard .
How does the URL Safeguard work?
If the domain contained in the link is not present in any of the lists, NoSpamProxy replaces the original link with a link that points to the Web Portal.
- NoSpamProxy replaces the original link with a link that points to the Web Portal.
- NoSpamProxy replaces the original link with a link that points to the Web Portal and blocks access to the original link.
In both cases, the e-ail delivered to the recipient contains only the rewritten link.
- If the link is classified as safe, access to the original URL is permitted and executed.
- If the link is classified as unsafe, access is denied. A notification about the incident will be added to the message tracking. Depending on the configuration, the administrator also receives a notification.
TIP: Blocked URLs can be unblocked by adding them to the local allowlist. The domain belonging to the blocked URL can be viewed on the Web Portal by the recipient of the e-mail after clicking on the rewritten link. The responsible administrator can then carry out the activation. A further delivery of the email by the communication partner is not necessary.
Frequently asked questions
What is a Protected Link?
The expression Protected Link is displayed instead of a URL if the display text contains a URL that can be copied into the browser and leads to a potentially harmful page.
In which cases are URLs rewritten?
The URL or the display text in the email is rewritten if the domain of the URL of the display text or the actual link is not on the NoSpamProxy Allowlist or the local allowlist.
What can I do if links to the Web Portal cannot be opened due to their length?
A long link to the Web Portal may mean that it cannot be opened, as it exceeds the length limit of some browsers due to the rewriting. The original URL cannot be tracked in the associated message track, even if tracking has been activated. Only a shortened version is displayed there. You can view the Fully Quallified Domain Name (FQDN) in the associated Message Track, on the URL Safeguard tab, provided that tracking has been activated (see Default partner settings). To prevent links from this domain from being rewritten in the future, add the corresponding domain to the local allowlist. See Setting up URL Safeguard.
