This setting is used to allow or refuse reception from 
specified addresses/domains.
To refuse reception from specified addresses/domains, 
select the [Reject Reception] key and touch the [OK] 
key.
When permitting only reception from the address or the 
domain that you program, touch the [Allow Reception] 
key and then the [OK] key.
To allow reception from all addresses/domains even 
when there are addresses/domains specified, select [All 
Invalid].

Up to 50 addresses/domains can be stored.

A maximum of 64 characters can be entered. After you 
have entered the address/domain, touch the [OK] key.

To store another address/domain, repeat the procedure 
from step 1. Addresses/domains will be stored in 
succession.

Touch the address or domain that you wish to delete in the 
list of stored addresses/domains. A confirmation message

• For the procedure for entering text, see 

"6. ENTERING TEXT" in the User's Guide.

• When there are no stored anti junk mail addresses, 

only the [Enter] key can be selected.

• If the first character of the entry is not "@", the entry 

is identified as an address. If the first character is 
"@", the entry is identified as a domain. 
([email protected] is treated as an address, and 
@xx.xxx.com is treated as a domain.)

• Storing an address specifies only that address. 

Storing a domain specifies all addresses that 
include that domain.
