- outsidetheparty 4y agoIt’s in case your marketing domain gets nailed for spamming, you don’t want your regular employees work email blacklisted.
- LukeShu 4y agoIn AT&T's case, it's because @att.com addresses were (are?) given to AT&T residential Internet customers, so they needed a separate domain so it's "clear" if an email is from AT&T itself or from a rando residential AT&T customer.
