Abstract

The invention provides a computer-implemented method for responding to an email message sent by a sender to an intended recipient. The method includes the steps of extracting the recipient email address from the initial email message and determining whether there exists a valid email account corresponding to the extracted recipient email address. When it is determined that no valid email account exists corresponding to the recipient email address, a response email message is generated and directed to the sender email address. The response email message not only indicates that the initial email message was undeliverable, but it includes supplemental information that may be of use to the sender. For example, the supplemental information may include advertisement information or search links that may or may not be contextually relevant to the content of the initial email.

Claims

1. A computer-implemented method for responding to an initial email message sent from a sender email address and directed to a second email address, the method comprising:

(a) extracting the second email address from the initial email message;

(b) determining that no valid email account exists corresponding to the second email address extracted from the initial email message; and

(c) generating a response email message directed to the sender email address, wherein the response email message includes supplemental information and information indicating that the initial email message was not delivered to the second email address.

2. The method of claim 1 wherein step (c) includes generating the response email message including supplemental information comprising advertising information.

3. The method of claim 1 wherein step (c) includes generating the response email message including supplemental information comprising a Uniform Resource Locator (URL) pointing to a web page that is accessible via a global communication network.

4. The method of claim 1 wherein step (b) comprises determining whether a domain name in the second email address exists in a Domain Name Server database.

5. The method of claim 1 wherein step (b) comprises determining whether a mail exchange record exists for a domain name in the second email address.

6. The method of claim 1 wherein step (b) comprises determining whether a username in the second email address is valid.

7. The method of claim 1 wherein step (c) comprises generating the response email message at a server computer selected from the group consisting of a sender email server, a recipient email server and a domain name server.

8. The method of claim 1 wherein step (b) comprises accessing a mail exchange record which provides a listing of one or more email servers associated with the second email address, and directing the initial email message to one or more of the email servers listed in the mail exchange record;

and

step (c) comprises generating the response email message at the one or more email servers to which the initial email message was directed.

9. The method of claim 1 further comprising recording the sender email address in a log.

10. The method of claim 1 wherein step (c) further comprises:

(c1) searching for keywords in the subject matter of the initial email message; and

(c2) generating the supplemental information to include information that is related to one or more keywords found in the subject matter of the initial email message.

12. The method of claim 10 wherein step (c2) further comprises generating the supplemental information at a server other than a sender email server or a recipient email server.

11. A computer-implemented method for responding to an initial email message sent from a sender email address and directed to a second email address, the method comprising:

(a) extracting the second email address from the initial email message;

(b) determining whether there exists a valid email account corresponding to the second email address extracted from the initial email message, wherein the determining includes one or more of;

(b1) determining whether a domain name in the second email address exists in a Domain Name Server database;

(b2) determining whether a mail exchange record exists for a domain name in the second email address; and

(b3) determining whether a usemame in the second email address is valid; and

(c) generating a response email message directed to the sender email address, wherein the response email message includes advertising information and information indicating that the initial email message was not delivered to the second email address, wherein generation of the response email message includes;

(c1) searching for keywords in the subject matter of the initial email message; and

(c2) generating the advertising information to include information that is related to one or more keywords found in the subject matter of the initial email message.

13. The method of claim 11 wherein step (c) further comprises generating the response email message at a server other than a sender email server or a recipient email server.

14. A computer-implemented method for responding to an initial email message sent from a sender email address and directed to a second email address associated with a domain that is not operable to receive incoming email messages, the method comprising:

(a) prior to the sending of the initial email message, configuring a mail exchange record for the domain associated with the second email address, where the mail exchange record is configured to point to a mail server;

(b) after the sending of the initial email message, determining the domain associated with the second email address;

(c) determining based on the mail exchange record of the domain determined in step (b) that a response to the initial email message is to be generated by the mail server indicated by the mail exchange record;

(d) generating a response email message at the mail server indicated by the mail exchange record, where the response email message is directed to the sender email address and includes;

information indicating that the initial email message was not delivered to the second email address; and

links to supplemental information that may be of interest to a sender of the initial email message, wherein the supplemental information is related to subject matter contained in the initial email message.
