Abstract

A communication terminal unit capable of identifying a message sender by comparing a source address attached to a received message with an address registered in a memory of the unit in advance, which can identify the message sender even if the source address has an error by regarding the erroneous source address to be the same as the registered address when the difference between these two addresses is within a predetermined permissible range.

Claims

1. A communication terminal capable of receiving a mail, comprising:

a memory which stores a mail address;

means for extracting a sender mail address contained in the received mail;

means for comparing the sender mail address with the mail address in the memory; and

means for determining that the sender mail address coincides with the mail address in the memory if the comparing means detects that the sender mail address coincides with the mail address in the memory except for difference of capital letter or small letter.

2. The communication terminal according to claim 1, wherein the memory stores a plurality of mail addresses, and the comparing means compares the sender mail address extracted by the extracting means with each of the mail addresses in the memory in turn until the determining means determines the sender mail address coincides with one of the mail addresses in the memory.

3. The communication terminal according to claim 1, further comprising:

means for displaying the mail address in the memory if the determining means determines that the sender mail address coincides with the mail address in the memory.

4. The communication terminal according to claim 1, further comprising:

means for displaying the sender mail address if the determining means determines that the sender mail address coincides with the mail address in the memory.

5. The communication terminal according to claim 1, further comprising:

means for displaying the sender mail address and a name of a sender of the received mail if the determining means determines that the sender mail address coincides with the mail address in the memory,

wherein the sender name is stored in the memory and associated with the mail address.

6. The communication terminal according to claim 1, further comprising:

means for displaying the mail address in the memory if the determining means determines that the sender mail address agrees with the mail address in the memory.

7. The communication terminal according to claim 1, further comprising:

means for displaying the sender mail address contained in the received mail if the determining means determines that the sender mail address agrees with the mail address in the memory.

12. The communication terminal according to claim 1, wherein the memory stores a plurality of mail addresses, and the comparing means compares the sender mail address extracted by the extracting means with each of the mail addresses in the memory in turn until the determining means determines the sender mail address coincides with one of the mail addresses in the memory.

8. A communication terminal capable of receiving a mail, comprising:

a memory which stores information including a mail address and a name, wherein the mail address is associated with the name;

means for extracting a sender mail address contained in the received mail;

means for comparing the sender mail address with the mail address in the memory;

means for determining that the sender mail address coincides with the mail address in the memory if the comparing means detects that the sender mail address coincides with the mail address in the memory except for difference of capital letter or small letter; and

means for displaying at least a portion of the stored information in the memory if the determining means determines that the sender mail address coincides with the mail address in the memory.

9. The communication terminal according to claim 8, wherein the displaying means displays the sender mail address contained in the received mail if there is no mail address, which coincides with the sender mail address, in the memory.

10. The communication terminal according to claim 8, wherein the memory stores a plurality of mail addresses, and the comparing means compares the sender mail address extracted by the extracting means with each of the mail addresses in the memory in turn until the determining means determines the sender mail address coincides with one of the mail addresses in the memory.

11. A communication terminal capable of receiving a mail, comprising:

a memory which stores a mail address;

means for extracting a sender mail address contained in the received mail;

means for comparing the sender mail address with the mail address in the memory to detect whether the sender mail address agrees with the mail address in the memory completely and whether the sender mail address agrees with the mail address in the memory except for difference of capital letter or small letter; and

means for determining that the sender mail address agrees with the mail address in the memory if the comparing means detects at least one of that the sender mail address agrees with the mail address in the memory completely and that the sender mail address agrees with the mail address in the memory except for difference of capital letter or small letter.
