Postmaster (email)
Postmaster is the local part (Engl. Local-part ) of an e-mail address after Internet standards such as RFC 822 and RFC 1123 , each domain , provided they have must email support. The term originated analogously to role accounts such as webmasters or newsmasters .
The address is intended to be able to contact someone who is responsible for the domain's e-mails under even the most adverse circumstances. For example, someone should be available at the address postmaster@example.com who can help if no e-mails are accepted at another e-mail address ending in @ example.com .
The RFC 5321 draft for the Simple Mail Transfer Protocol allows e-mails to this address to be rejected in the event of an attack on the mail server . However, it also requires that e-mails to this address must not be rejected because the address is given without the name of the domain. Since both are already included in RFC 2821 , they can be considered generally accepted, although the RFC 821 standard does not mention anything of the kind.
Although the delivery of e-mails to this address is deliberately made particularly easy, it is not particularly attractive for distributors of spam. The purpose of these is to ensure that your e-mails are responded to as requested. This is least to be expected of people who read emails sent to postmasters, because a certain amount of experience and caution is to be assumed. In addition, they are the ones who are most likely to prevent e-mails from this sender from being delivered to other addresses.
Like other e-mail addresses for special purposes, such as RFC 2142 , this does not have to be assigned to a user account or an individual. For example, it can also be an alias under which e-mails are received and delivered to several people.
