Abstract

Email server side or client side components either remove email attachments from the relevant email, or identify the attachment while the email is being composed and makes the attachment available from a secure website or file hosting site. The recipient then receives instructions in the email and links to access the attachments rather than the attachments themselves. Email attachment size limitations are overcome for sender/recipient mail systems. Also, file type limitations related to email attachments are overcome, provides improved attachment security, and reduces email bandwidth costs.

Claims

1. A method of automatically removing an email file attachment, comprising:

prior to transmission of an email from a physical user device to a physical email server, detecting, with said physical user device, of a file attachment to said email;

prior to transmission of said email from said physical user device to said physical email server and in response to said detection of said file attachment to said email, inserting a link to said file attachment in said email, said link being coded to an Internet Protocol (IP) address of an addressed recipient of said email, wherein said link is accessible only by a device with said IP address; and

moving said file attachment from said physical user device to a physical download server for retrieval of said file attachment via said link, wherein said moving comprises removing said file attachment from said email.

2. The method of automatically removing an email file attachment according to claim 1, wherein:

said physical download server is accessible by a physical recipient device via an Internet.

3. The method of automatically removing an email file attachment according to claim 1, wherein:

said inserting said link occurs based on at least one file-related parameter.

4. The method of automatically removing an email file attachment according to claim 3, wherein:

said file-related parameter is a file size greater than a predetermined threshold size.

5. The method of automatically removing an email file attachment according to claim 3, wherein:

said file-related parameter is a file type matching a predetermined file type.

6. The method of automatically removing an email file attachment according to claim 1, wherein:

said moving said file attachment is performed before said inserting said link.

7. The method of automatically removing an email file attachment according to claim 1, wherein:

said removed file attachment is moved to said physical download server via the Internet.

8. The method of automatically removing an email file attachment according to claim 1, further comprising:

routing said email to a physical recipient device.
