Great questions! Let me see if I can tackle them in order so I don’t get lost
- This is possible.
- It is. In DirectAdmin (Lisa, Longhorn) go to Advanced Features and then Catch-All E-mail. To change the domain you are configuring at the time, look at the top right for a drop-down box. The process is actually similar for cPanel (our older servers).
- Only per domain, but not one that covers all domains in an account. Of course, you can configure the catch-all on each domain to point to the same recipient.
Be careful if using a catch-all to forward all email to third party email services. We commonly see this used for Gmail and while it mostly works and almost no one notices an issue, Google does reject forwarded email for domains that specify a reject in their DMARC record, and this is often for major services like Facebook, eBay, etc. You can miss emails because third party recipient services reject them where we might have delivered them to your inbox with us.
