You may make it use by loading to CPU57 from an apparatus and starting.
[0026]
[Mail Address Change Instruction Processing] In the facsimile according to the first embodiment, the telephone number of the user is set by default so that the user can send and receive e-mail without setting the mail address. □□ (approx. 10 digits) + L-mode identifier (@ pipopa.ne.jp), for example, an e-mail address of 0312345678@pipopa.ne.jp is set in advance for devices used at home with a telephone number of 0123345678 Has been. For this reason, when the user installs a facsimile or turns on the power, the user is urged to change the mail address to a number other than a number as soon as possible.
[0027]
First, the CPU 57 determines whether or not a preset period, for example, one day has passed (S12). Then, after the elapse of a predetermined period (S12: Yes), the mail address stored in the memory (EEPROM) 50 is acquired (S14), and the character string on the left side (identifier) of the mail address is extracted. To do.
[0028]
The CPU 57 determines whether or not the identification part of the mail address consists of numbers (S18). Here, when the identification part includes alphabets or the like other than numbers (S18: No), the processing is ended because the mail address has already been changed by the user.
[0029]
On the other hand, when the identification part is entirely composed of numbers (S18: Yes), a warning “Please change your mail address to prevent spam mail delivery” is displayed on the display part 21 as shown in FIG. Is displayed (S20). At this time, the change of the mail address may be prompted by voice. Then, it is determined whether there is a key operation (S22). If there is a key operation (S22: Yes), the warning display is interrupted and the process proceeds to the process corresponding to the key operation. Note that the process of prompting the change may be performed only when the facsimile is installed (when the power is turned on).
[0030]
According to the facsimile of the first embodiment, the identification part □□□□□□□□□□ (around 10 digits) in the email address □□□□□□□□□□@pipopa.ne.jp It is determined whether or not the initial setting has not been changed, and when it is determined that the initial setting is made only of numbers, the mail address is urged to be changed. For this reason, it becomes possible for the user to prevent the distribution of spam mails by changing the identification part to alphabets or the like.
[0031]
[Mail Address Change Processing] In the facsimile according to the first embodiment, even when the mail address is changed, an address consisting only of alphabets that may cause spam mail to be delivered, which is not recommended in the ROM 50.

[0032]
When the CPU 57 displays the function selection menu for setting my address shown in FIG. 6B for starting the change of the mail address (S52), the CPU 57 performs "registration" by operating the cursor movement button (scroll button) 22c. When the L button 22b for performing the L mode operation is pressed in a state where “/ change” is highlighted, it is assumed that the address change is selected (S54: Yes), and the mail address change process is started.
[0033]
The CPU 57 first initializes the mail address held in the memory (EEPROM) 50 (S56), and waits for key input (S58). If there is a key input (S58: Yes), it is determined whether or not the key input is a valid code such as a number or alphabet (S60), and it is not an input (valid code) that cannot be used for a mail address such as "#". In this case (S60: No), a key input acceptance refusal sound is made (S64), and the process returns to S58 and waits for key input. On the other hand, if a valid input has been made (S60: Yes), it is determined whether the key input is an input completion code (S62). Until the input completion code is input (S62: No), the input code is written in the memory (S66). Then, it is determined whether the maximum number of digits (for example, 10 digits) has been input (S68). Until the maximum size digit is input (S68: No), the process returns to S58 and waits for the next key input. Note that the maximum number of digits may be 11 digits as in a mobile phone.
[0034]
Here, if the maximum number of digits has been entered (S68: Yes), or if an input completion code has been entered prior to the entry of the maximum size (S62: Yes), the entered email address @ The character string of the left part (identification part) is extracted (S70). Then, it is determined whether or not the identification part is entirely composed of numbers (S72). If the identification part is composed only of numbers (S72: Yes), “this input is input to the display unit 21 as shown in FIG. 6C”. An address is not recommended, please read the instruction manual carefully and re-enter ". A re-input warning is displayed (S78). At this time, re-input of the mail address may be prompted by voice. Then, it is determined whether or not there is a key operation (S80). If there is a key operation (S80: Yes), the e-mail address change is temporarily interrupted, the address is returned to before the change (S84), and the process is performed. finish.
[0035]
On the other hand, if the identification part of the input mail address includes anything other than numbers (S72: No), it is next determined whether or not the identification part of the mail address is entirely composed of alphabets (S74). Here, when it consists entirely of alphabets (S74: Yes), the process proceeds to S78, and a re-input warning is given as described above.
[0036]
In the first embodiment, it is determined whether the identification part of the changed mail address is composed only of alphabets, and when it is determined that the identification part is composed only of alphabets, it is urged to change the mail address. In other words, even if the email address is changed, the identification part □□□□□□□□□□ in the email address □□□□□□□□□□@pipopa.ne.jp The combination is 26 × 2 (the alphabet number of A to Z and a to z) to the 10th power, and the distribution of the spam mail cannot be completely prevented. For this reason, when it is judged that it consists only of the alphabet, it is prompted to change the mail address, and the address has a number, and further,-,. By mixing symbols such as (dot) and _, spam mails can be completely prevented from being delivered.
[0037]
If the identification part of the input mail address includes anything other than alphabetic characters (S74: No), then the non-recommended address (typical female name, It is determined whether or not celebrity names, abbreviations, and names often found in telephone books are included (S76). If a non-recommended address is included (S76: Yes), the process proceeds to S78 and a re-input warning is performed as described above. On the other hand, when the non-recommended address is not included (S76: No), the changing process is terminated and the changing process to the mail address (S82) is started.
[0038]
In the first embodiment, an easily conceivable address such as the name of a woman, the name of a celebrity, or a common name is stored in advance as a non-recommended address. Then, it is determined whether the changed e-mail address identification unit includes a non-recommended address, and when it is determined that the non-recommended address is included, the e-mail address is changed. By avoiding addresses consisting of female names, names of celebrities, common names, etc., spam mails can be completely prevented from being delivered.
[0039]
In the above-described embodiment, the non-recommended address is held in the ROM 50. At the same time, when the L-mode control information is updated from the gateway 16 side via the public line 15, the non-recommended address is also distributed. However, it may be held in the EEPROM 52 on the facsimile side to avoid using the distributed non-recommended address as a mail address.
