Most email programs have a blocking rules function - "if the email is or has xxxx then do this with it."

In MS Outlook it's under -> Tools (menu bar) --> Rules Wizard

Netscape -> Tools (menu bar) --> Message Filters

Eudora -> Tools (menu bar)

Pegasus -> Tools (menu bar) --> Mail Filtering rules OR

or select an email as an example then hit the Filtering button

Pine: type 'S' then 'R'

Thunderbird -> Tools (menu bar) --> Message Filters

Is 24 bit block a better addressing scheme in computer networking than a 16 bit block?

There is nothing inherently "better" about the 24-bit block address space. If by "better" you mean "able to contain more addresses," then yes. 24-, 20-, and 16-bit network ranges are also known as class A, B, and C, respectively, and refer to ranges of IP addresses. Every device that directly accesses the internet has a unique IP address. IP addresses are commonly represented as a set of four numbers (called "octets") separated by periods, e.g. "145.94.112.18". Each of the numbers can be in the range of 0-255, and some sets of numbers have special meanings. The range of IP addresses is divided up into three classes based on the first octet. If the first octet is from 0-127 it's class A, 128-191 is class B, and 192-223 is class C. The octets of an IP address are divided up into a network portion and a host portion depending on what class it is. In class A addresses, the first octet is the network portion and the remaining three are the host portion. For class B, it's two-and-two, and for class C the first three are network and the remaining one is host. What does this network/host division mean? Generally, large entities (such as a company) are assigned a single network block of IP addresses. For instance, IBM is in control of the 9.0.0.0 network block. This is a class A address, meaning that the network portion is 9 and the rest is the host portion. IBM can divide this space up (using a technique called subnetting) any way it sees fit. Every computer within IBM would have a different ip in the 9 network, e.g. 9.4.109.10, 9.212.34.88. A class A (or 24-bit) block address has three octets it can use to create different IP addresses, such as "9.0-255.0-255.0-255". A class C (or 16-bit) block address has only one octet it can use to create different IP addresses, such as "192.168.1.0-255". You can clearly see that a class C block address contains less potential addresses than a class A or B block address. This doesn't make class C addresses any worse than class A ones, though. A small business (or a home network) doesn't need a million different IP addresses, so a 16-bit block address is perfect for them and if they had a class A or B all those numbers would be wasted.


What is indexed addressing mode?

When stored in contiguous blocks, data usually has a base address. Accessing any data from the block requires an offset to the base address which is achieved through an index. The adding of an offset to the base address is called indexed addressing.

What three factors affects your role in processing incoming mail?

New technologies are able to locate the correct destination address block on the image of an envelope, flat-size mailpiece or parcel. The software automatically parses & recognizes the fields within this address block. It is designed to deal with different address block structures & automatically reads the variety of fields & formats that may be encountered on a mailpiece.
