Why is setting up an out-of-office assistant / autoresponder not allowed?
Unfortunately, the e-mails you receive always include some spam e-mails. If spam e-mails are also answered automatically, the senders learn that there really is a person behind this e-mail address. As a result, even more spam is sent to this person. Those automatic replies are sent by our mail server, which then gets a bad "digital reputation" on the internet – in the worst case, e-mails no longer reach their recipients at all.
