Rely on us! Our server-side security systems are always up to date, meaning they react immediately to current threats and protect your mailboxes using the highest security standards. Despite all of the best security measures, however, it can happen in exceptional cases that spam and phishing emails find their way into your mailbox. Read our Digital Guide article to learn how to recognize and deal with these emails and how to protect your corporate or home network from them. Spam is unfortunately a widespread phenomenon. These unwanted messages are not only annoying – they can also contain harmful phishing links or Trojans disguised as attachments. Thanks to the IONOS email spam filters and antivirus system, emails with malicious attachments or suspicious content are intercepted before they ever reach your mailbox. If you continue to receive spam messages regularly, you can make further settings by logging in to your IONOS Webmail. Creating personalized blacklists and whitelists to refine and customize your spam protection is easy. Mail from senders in the blacklist is automatically deleted, although you can remove a sender from the blacklist at any time.
