In a chilling indication of how fastmail is spiraling out of control,
my mailbox this morning contained 6 emails that were addressed
to other people who have domains hosted at Fastmail. (I checked the MX records for all 3 domains.) The person addressed at each domain happens to be my fastmail username. I assume that fastmail cannot find these domains and the mail defaults to the fastmail user with that name (insane).
So if you use any of the following domains:
mackraz.com
trickbit.to
brooker.us
You need to check with Fastmail immediately to straighten this out.
I guess what most disturbs me is that if the system cannot find
joeblow@whateverdomain.com it throws the mail into
joeblow@fastmail.fm 's mailbox.
