A ‘catch-all’ email account collects all messages addressed to non-specified usernames at the domain.
For example:
If your domain is www.your-domain.com and you have the only email account for this domain configured as a catch-all mailbox, namely catchall@your-domain.com, all emails addressed to this domain (anything@your-domain.com) will be routed to the catch-all mailbox.
The mail catch-all feature has become a valuable tool for larger businesses. Emails are downloaded from Hetzner’s server to a company’s mail server and then distributed to mailboxes throughout the company by an internal server. This eliminates the need for each user to connect to the internet and download new emails, which will further assist in managing your bandwidth more effectively.
The disadvantages of having a catch-all mailbox are that you are more susceptible to spam. Spammers generate emails to random addresses at your-domain.com, knowing that may companies have catch-all enabled. It is possible to disable the catch-all mailbox if this becomes relevant to you.
Note: All web hosting packages are by default configured to have the catch-all mailbox disabled. Should you wish to make use of this feature, please setup your catch-all mailbox.
