Abstract

A handheld terminal has a function of saving a received electronic mail into a memory. A CPU specifies a sender of the electronic mail received this time, and detects from the memory the electronic mail received from this sender in the past. If the specified sender is registered on a list of candidates to be deleted, and a receiving date of the electronic mail detected from the memory is older than a week or more days, the CPU deletes the detected electronic mail from the memory.

Claims

1. A communication terminal that saves a received electronic mail into a memory, comprising:

a detector for detecting from said memory the electronic mail received in the past from a specific sender who is a sender of a noticed electronic mail;

a first determiner for determining whether or not a first condition is satisfied between said noticed electronic mail and the electronic mail detected by said detector; and

a first deletor for deleting the electronic mail detected by said detector when a determination result of said first determiner is positive.

2. A communication terminal according to claim 1, further comprising a second determiner for determining whether or not said specific sender satisfies a second condition, wherein said first determiner performs a determining operation when a determination result of said second determiner is positive.

3. A communication terminal according to claim 2, wherein said second condition includes a registering condition that an identifying code of said specific sender is registered in a first register.

4. A communication terminal according to claim 3, further comprising:

a third determiner for determining whether or not the identifying code of said specific sender is registered in a second register when said registering condition is not satisfied, and

a first registerer for registering the identifying code of said specific sender into said first register when a determination result of said third determiner is negative.

5. A communication terminal according to claim 4, further comprising:

an acceptor for accepting an input of a desired identifying code;

a second registerer for registering said desired identifying code into said first register;

an ouputter for outputting a message when said desired identifying code is registered in said second register; and

a second deletor for deleting said desired identifying code from said second register corresponding to the input in response to said message.

6. A communication terminal according to claim 1, wherein said first condition includes a first threshold value condition that a difference between a receiving date of said noticed electronic mail and a receiving data of the electronic mail detected by said detector exceeds a first threshold value.

7. A communication terminal according to claim 1, wherein said noticed electronic mail is the latest electronic mail, the electronic mail detected by said detector is the oldest electronic mail, and said first condition includes a second threshold value condition that the number of electronic mails existing between said latest electronic mail and said oldest electronic mail out of the electronic mails from said specific sender exceeds a second threshold value.

8. A communication terminal according to claim 1, further comprising an excluder for excluding an unread electronic mail from a candidate to be deleted out of the electronic mails detected by said detector.

9. A mail managing method that manages a received electronic mail, comprising the steps of:

(a) detecting from a memory the electronic mail received in the past from a specific sender who is a sender of a noticed electronic mail;

(b) determining whether or not a first condition is satisfied between said noticed electronic mail and the electronic mail detected by said step (a); and

(c) deleting the electronic mail detected by said step (a) when a determination result of said step (b) is positive.
