<![CDATA[Catch-all mailboxes are being identified by many vendors these days]]>Just a FYI:

I see more and more checks in my mail logs by service providers like helo@gamalogic.com or check@kickboxio.net if my email server has a "catch-all" mailbox.

They send emails either to a random address like 4a47f57a869a0ea0@domain.com or at the same time to such random address and the address you used for e.g. registration on a website.

I have long switched from catch-all mailboxes to aliases with wildcards so the emails mentioned above are rejected; they would get delivered to a catch-all mailbox (and such successful delivery will be monitored).

If you do use catch-all mailboxes and have problems with registration at websites and / or reputation of your mail server, you might want to consider a switch.

I used a catchall because I relied on it (for convenience, but still). I have now switched to wildcard aliases immediately and set up a catchall I will never look at.

I appreciate the posting!
