With the site redesign we hadn't gotten around to re-add the alternate domains to Mailinator (i.e., these are domains that are equivalent to @mailinator.com, so sending email to email@example.com is the same as sending email to firstname.lastname@example.org).
The delay was in part this was due to all the new domains we added. Well, here is the list. Note this is NOT the complete list - because in general, we don't know what the complete list is. Anyone (even you!) can point any domain you like at mailinator.com and it will happily accept the email sent to that domain. So if you have a domain or two laying around - feel free to point it to us! (and let us know!)
Here's the list ! (note: capitalization doesn't matter, just added for effect)
anythingYouWant@mailinator.com is the same as:
We'll get these on the site very soon.
