Disfigured so as to guard the /real/ eddress from the spambots. Some
people munge their eddress in different ways, such as:





All will avoid the spambots, BUT the last one is incorrect because it
leaves the ISP's name and any spam mail sent to the eddress will,
therefore, sit on the mail server until it is either delivered (not
likely) or deleted by the server which can take weeks depending upon how
the server is configured. The rest correctly munge the ISP name so mail
goes directly to the trash instead of sitting around taking up server
space while delivery is attempted over and over again.


Cyberwizard you made a minor mistake. All but the LAST one is incorrect. A
valid domain will allow the MTA (mail transport agent) to attempt to deliver
the mail, trigger an immediate bounce. (specifically a 550 user unknown
error)

A bogus domain will trigger a variety of errors, based on what bogus domain
you chose, non-existent domains, or hosts trigger 500 series fatal errors.
Lame delegation, network reachable trigger 400 series errors.

400 series errors are the least desirable because they can on the mail
server's mail queue for up to a week, 500 series are processed immediately
and do not chew up disk space.
