Abstract: A system and a process for performing identified modifications of content in an e-mail message at a server or server farm electronically distal from an e-mail origin site. The process acts so that: a) the distal server or server farm pointed to by an MX record of a short domain in the domain name server system; and b) an e-mail message comprising a recipient e-mail address combined with said short domain as a suffix.

Abstract: A request to resolve an IP address is received by a Domain Name Server (DNS). A record, such as an MX record, relating to the request is obtained that comprises a unique label (e.g. record=customer-com.mail.messaging.com) that is used in determining how to resolve the request. The unique label portion of the record (e.g. customer-com) is used to identify information relating to the request such as a version of software/service to use to handle the request, a region used to handle the request, and the like. The same record may be used to direct a request to a different version and/or different region. For example, without changing the record, a request at one time may access a first version/region and a request at a different time access a different version/region.

Abstract: The multipart/report Multipurpose Internet Mail Extensions (MIME) media type is a general "family" or "container" type for electronic mail reports of any kind. Although this memo defines only the use of the multipart/report media type with respect to delivery status reports, mail processing programs will benefit if a single media type is used for all kinds of reports. This memo obsoletes "The Multipart/Report Content Type for the Reporting of Mail System Administrative Messages", RFC 3462, and marks RFC 3462 and its predecessor as "Historic". [STANDARDS-TRACK]

Abstract: In 2006, the IETF published a suite of protocol documents comprising the Sender Policy Framework (SPF) and Sender ID: two proposed email authentication protocols. Both of these protocols enable one to publish, via the Domain Name System, a policy declaring which mail servers were authorized to send email on behalf of the domain name being queried. There was concern that the two would conflict in some significant operational situations, interfering with message delivery. The IESG required all of these documents (RFC 4405, RFC 4406, RFC 4407, and RFC 4408) to be published as Experimental RFCs and requested that the community observe deployment and operation of the protocols over a period of two years from the date of publication to determine a reasonable path forward. After six years, sufficient experience and evidence have been collected that the experiments thus created can be considered concluded. This document presents those findings. This document is not an Internet Standards Track specification; it is published for informational purposes.

Abstract: Disclosed is method for identifying the state of a mail, comprising: a mail server determining if the mail transmitted by a sender terminal is transmitted to a receiver terminal that is in a same mail system with the sender terminal, if yes, generating a mail identification marker corresponding to the mail, and adding the mail identification marker and sender terminal address information of the mail to a header of the mail then transmitting to the corresponding receiver terminal; when the receiver terminal reads the mail, the mail server writing mail information of the mail into a mail log information table, and setting the current state of the mail as read. Implementation of the present invention allows for each mail to have independent state information stored in the mail log information table, for use to query the state of each mail after transmitting the mail, thus learning accurately if the terminal receiving the mail has read the mail, thus increasing for the user convenience of using mail correspondence.

Abstract: Disclosed is a virtual address-based mailbox bulk-mailing method, comprising: a sender transmits a mail to a mail transfer agent via a mail user agent; the mail transfer agent generates a query request on the basis of the virtual mail address, and transmits the query request to a mail address processor; the mail address processor looks up a physical mail address on the basis of the virtual mail address, and transmits the physical mail address to the mail transfer agent; and, the mail transfer agent forwards the mail to a recipient on the basis of the physical mail address. Also disclosed is a mailbox bulk-mailing system. Employment of the present invention, by establishing the virtual mail address via a specific coding technology, also by allocating a mapped virtual mail address to each organizational structure unit, prevents the establishment of individual mail lists and mailbox maintenance for each organizational structure unit, thus greatly increasing the management efficiency of an enterprise having a complex organizational structure without occupying additional system resources.

Abstract: Disclosed is a mail process method including: a mail server obtains the corresponding mail characteristic information according to the different mail type, and sends the characteristic information to a center server; the center server determines whether a mail corresponding with the characteristic information is a spam according to the mail characteristic information, and returns the determination result to the mail server. Corresponding, the invention also provides a mail process system. Utilizing embodiments of the invention, the mail server can real-time upload a mail characteristic waiting for check, and immediately obtain a determination result returning from the center server, the invention has highly time efficiency. The invention extracts the different characteristic according to the different format information within a mail, provides the center server to perform clustering and classifying, and determines whether the mail is a spam. Also, the center server can obtain enough data quantity through the query request sent from the mail server that processes a mass of mails, and perform clustering and classifying, which greatly improves the filtering effect of the center server.

Abstract: With the rapid development of internet technology, e-mail is becoming a popular, convenient, economical way of communication. At the same time, the spam is flooding the internet. To solve this problem, the e-mail filtering technology based on e-mail gateway is widely used but mail gateway is apart from mail server and cannot get the mail account which is in the mail server, so the e-mail filtering products based on e-mail gateway always has no efficient way to manage mail account. This paper provides a new method to maintain mail account information for mail gateway. This method not only manages mail account from a number of different mail servers, but also filters the e-mail whose destination address is not existent. So the technology proposed in this paper can reduce the burden on the e-mail network.
