Yes, I've always done this.  The other downside is that the anti-spam
   laws were not designed to protect people in this mode: You can only
   unsub one address at a time, not a whole domain.  Automation can help
   that, but it is a pain.
   Email clients are spotty on multiple identity support.  Thunderbird
   supports many accounts and identities, but it can get a little confused
   sometimes.  The biggest bug gotcha is that when you resume a draft, it
   will often choose a random from identity.  I've accidentally mixed up
   realms in ways I seriously did not intend.  I try to address check
   every message.  I've been meaning to dig into Thunderbird to fix it,
   but low on my priority list.

For those not yet familiar with the convenience and utility of email
catch-all domains, they provides very convenient "canary" flagging of
who sold your email address to a third party marketer.

I.e., when you make a purchase at ebaysmells.com, and your email address
is for example [2]ebaysmells.com@myfunkydomain.me, then when, some months
later you receive an email from Zhing Wha Good Electronics $2 sale, and
that email is sent to [3]ebaysmells.com@myfunkydomain.me, you can have a
fair idea that either ebaysmells.com, or the shop/person you made your
original purchase from, is attempting to make opportunistic use of your
email address.

There are a couple issues with this feature however, which are mostly
evident to anyone who uses them:

- When you are legimitely emailed from the web shop, news media provider
  or other, then one wants or often enough actually needs, to reply to
  the sender using as a From address, the To address they used to email
  you. Not doing so can easily mean no response as your normal email
  address gets completely lost and not tracked in their CRM system.

- As one solution, some email clients can be configured to always reply
  From the same address To which the email was sent.

- This gives rise to the next problem which I keep slipping up on since
  I changed my MUA config, that my canary email addresses are being used
  as the From address when I forward emaisl, rather than just when I
  reply which is what I thought I'd configured. This may not be
  configurable, which would mean remembering to manually change the From
  address every time I forward an email.


I send this in the expectation that some may like to be aware of this
feature of domain management, when you own/ control your own domain.
Being able to rattle off a random (to the other person) but traceable
(by you) email address at conferences, to business people etc, is quite
a handy thing to be able to do.

Enjoy,
