RFC2142 Common Mailbox Names

The name postmaster is required by RFC2822 and all sites must accept mail to that address. Another RFC, RFC2142, takes the concept of having a generalized postmaster address one step further by recognizing other roles, such as abuse, info, and marketing. For example, most web sites that sell products also accept email to the address sales, which is now a frequently used, generalized email address.

Table 12-1 shows all the newly required addresses defined by RFC2142. Of these, only postmaster is treated in a case-insensitive manner by sendmail.[205] That is, mail to postmaster, Postmaster, POSTMASTER, and PoStMaStEr will all be delivered to the same person.
