If you have written support, bugs, feedback, or sales since last friday (where macromates.com was moved to a new account on a new server with new software and a new IP, which did break a few things) your email has bounced (as you probably know). The problem will hopefully be fixed in a few hours (I’ll update this entry when it is fixed).
In the meantime feel free to (re)send to allan (at this domain).
Sorry about the inconvenience it may have caused you.
Update: The aliases should once again work. And just to clarify, “new account” only means a new user account at TextDrive, not that I have left this great hosting company!
