E-mail addresses

E-mail addresses can be almost any combination of human names and domain names within the rules of e-mail addresses:

Address Purpose
johndoe@example.com a random private person
janedoe@acme.example an employee of company Acme

Note that .s are usually ignored (i.e. jane.doe@example.com) and + mail as well (i.e. janedoe+urgent@example.com) hence both schemes are allowed.

Generic addresses

Common generic local parts are also allowed. This list is not exhaustive at this point, but here to provide some guidance.

Address Purpose
noreply@example.com Commonly used email company mailbox
info@example.com Commonly used company public mailbox
mailer-demon@example.com System mailbox
postmaster@example.com System mailbox
abuse@example.com Abuse mailbox
webmaster@example.com Homepage author mailbox, often from the 90s
