Many of our customers forward mails, for example from info@your-company.com to a private address at Hotmail, GMX or Gmail. Unfortunately, spam is forwarded along with the real mails. To the recipient it then looks as if our server were sending the spam. Providers such as Microsoft block such servers, and after that even your perfectly normal mails no longer arrive there.
That is why the Mail Quarantine is now available on all Linux web hosting servers: forwardings that our spam filter recognises as spam are held back instead of being sent on. You see these mails in your hosting control panel and decide for yourself what happens to them.
In a nutshell: the key terms
Forwarding: A mail to your address is automatically sent on to another address, for example to your private mailbox.
Spam filter: Checks every incoming mail and assigns a spam score. Above a certain score the mail counts as spam.
Quarantine: A protected area where forwardings recognised as spam are kept for a while instead of being sent on.
Whitelist: A list of senders you trust. Mails from these senders are always forwarded.
Your benefits at a glance

Nothing gets lostEvery mail still arrives in your own mailbox. Only the copy intended for the forwarding is held back.

Deliver with one clickIf an important mail is among them, deliver it to the forwarding address with one click, singly or several at once.

Good to know
You do not need to switch anything on. The Mail Quarantine is already active on all Linux web hosting servers.
Mails you send yourself and mails in your mailboxes are not affected.
Even more reliable than forwarding: set up your mailbox directly in your mail program or on your smartphone (IMAP). Then no mails pass through third-party servers.
