only (e.g. areamgr requests or whatever). In the future, they could be extended
to echomail areas too, if that's desirable.

For now, it's really intended for ticket-FileFix.

Anyway, NetMail can be received for the robot-name@<your-ftn-address> and
the mail message will be stored in the Synchronet "mail" base. The recipient
extension will be absent since there is no valid user account associated with
the robot. Robot names supercede other user names/aliases for received netmail.
If one or more netmail messages were imported for a robot and that robot has
a semaphore path/filename specified (e.g. to trigger a timed event), then that
semaphore will be "touched" before SBBSecho exits.
One weird anomly with this is if attached files are received for robots, those
files will be stored in data/user/0000.in. The altnerative is to just ignore
file attachments sent to robots.

The echofg supprot for robots is still yet to be added. In the mean time, you
can add robots to your sbbsecho.ini like so:
[robot:<name>]
semfile=/path/to/semfile

Incremented version to 3.11.
