Advantages and disadvantages of a collective account

The advantage of a collective mailbox is that no e-mail sent to a domain is lost. Especially for companies these mailboxes are useful to receive mails from prospective customers or customers who made a mistake when entering their address. However, setting up a collective mailbox has a serious disadvantage. E-mails whose addresses are randomly generated by spammers also end up in this mailbox. This means that spam mails will be delivered in any case. In order to prevent delivery, rules must be set up for this mailbox that are used to sort out the incoming spam mails.
