Strange, I thought the root name was always limited to 8 characters maximum even in v4.41 and earlier, I have no idea how that worked. By default this is the set to create a 8 character root using the ~d~d.101, I have no idea how ~8~d.101 would work in creating a lot of messages in the queue.

(note: this is not necessarily the To: field)

~n The sender's user name in its simplest form
~b The sender's bindery id, as a long hex integer
~8 The first 8 chars in the sender's username
~y The time and date in RFC-822 format
~d A random integer, expressed as 4 hex digits
