What Is Spam Mail

What is spam, where does it come from, and why do I

receive it?

Spam email is a form of commercial advertising which is

economically viable because email is a very cost-

effective medium for the sender. If just a fraction of

the recipients of a spam message purchase the advertised

product, the spammers are making money and the spam

problem is perpetuated.

Spammers harvest recipient addresses from publicly

accessible sources, use programs to collect addresses on

the web, and simply use dictionaries to make automated

guesses at common usernames at a given domain.

Spamming is politically debated in several countries,

and has been legislated some places with varying

results. Spammers often conceal or forge the origin of

their messages to circumvent laws, service provider

regulations, and anti-spammer lists used by anti-spam

software.

At the present more than 95% of email messages sent

worldwide is believed to be spam, making spam fighting

tools increasingly important to all users of email.

Spam and viruses

Spam is increasingly sent from computers infected by

computer viruses. Virus-makers and spammers are

combining their efforts to compromise innocent computer

users’ systems and converting them into spam-sending

“drones” or “zombies”. These malicious programs spread

rapidly and generate massive amounts of spam pretending

to be sent from legitimate addresses.

It’s important for all computer owners to install and

maintain anti-virus software to avoid having their

computer infected and possibly become a source of spam

without their knowing.

Effects of spam

Aside from the amount of junk arriving in the Inboxes of

millions of innocent email users every day, spam can

have a more indirect and serious effect on email

services and their users.

Runbox has, like most email services, been a victim of

forgery by spammers using specially designed software to

generate false email headers and From addresses. Using

various server names and domains, they confuse domain

administrators, email services, and spam victims,

concealing the true origin of the messages. See

Wikipedia: E-mail_spoofing for more.

Hijacking of real users’ addresses or email accounts is

also common. Typically these messages will have the From

field showing something like “Lisa W Harold”

<info@runbox.com>. Please note that such messages have

no actual connection to Runbox (to see what a real

Runbox header looks like, look at this example). Runbox

does not in any way distribute our customers’ email

addresses, and is not a source of spam — directly or

indirectly.

Several email users have been affected by falsified

messages claiming to be from the service’s

administrators, stating that users’ account are closed

and require some action by the user to be reopened. Such

messages often contain viruses and should be ignored or

deleted.

When hijackers succeed in sending spam via an email

services, it can be temporarily blocked by other

services and private domains who try to protect

themselves. Runbox does everything we can to prevent

this, but it’s important that email users protect their

own account with strong passwords to prevent their

account being hijacked. See Tips for choosing and

protecting passwords for more information.

If you have had email sent from Runbox blocked by the

receiving service, please contact Runbox Support, and

also file a complaint to the postmaster or support desk

of the domain in question. Often, setting your From

address under preferences as @runbox.no or @runbox.us

will circumvent such domain blocks (all Runbox addresses

are synonymous on the .com, .no, and .us top level

domains).

Phishing

An increasingly common phenomenon is “phishing”, where

messages appearing to be sent from e.g. legitimate

financial institutions attempt to trick recipients into

“verifying” sensitive data (such as credit card

information) on fraudulent web sites.

Legitimate services will rarely (if ever) send messages

requesting you to click a link and provide personal or

sensitive information. Be sure to verify the source of

the message before complying with such a request.

If you receive messages claiming to originate with

payment services such as PayPal, eBay, financial

institutions, or even Runbox, please verify that the

message is indeed sent from the service in question:

Look at the links in the message in plain text (not

HTML) view. Verify that the actual link contains the

domain name (e.g. runbox.com or paypal.com), and not

another domain name or IP address, by hovering the mouse

pointer over the link while looking at the status bar of

your browser. Remember that links in an HTML message may

be “disguised” and link to a different server than it

appears to do.
Check the message headers. Look at the IP address of the

sending server and verify that it resolves to the

correct domain and country by using a service such as

DNSstuff.
Falsified messages will rarely address you by name or

provide any personal information about you except your

email address, because the senders do not have access to

such information.
See Wikipedia: Phishing for more information.
In the wake of the increased onslaught of junk clogging

mailboxes, aggravation and frustration has caused some

misguided accusations and misconceptions about how spam

is generated and sent. Runbox is dedicated to fighting

spam as effectively and unintrusively as possible, and

in our Terms of Service strictly prohibits our users

from sending any type of spam through Runbox.

What does Runbox do to fight spam?

Runbox runs restricted access servers only. This means

that it is impossible to send mail from us without

logging in as a registered user, and we can trace every

single mail orginating from our system.
Runbox supports the Sender Policy Framework for

verifying the senders of email messages. See Wikipedia

for more information.
Runbox offers state of the art spam protection to all

our users. It is a unique combination of the renowned

points-based SpamAssassin, and the “intelligent”

statistical spam filter Dspam.
Runbox checks major databases of spam originators such

as the The Spam and Open Relay Blocking System, Spamhaus

Zen Block List and Razor. Users can block senders and

domains themselves using the Block sender button on

mails, or the list directly, under Manager:Filter.
Runbox enforces strict quotas on outgoing email and does

not allow trial users (those who have not yet paid for

their account) to send email to more than 20 recipients

per day.
Complaints about users sent to abuse@runbox.com are

reviewed daily, and a single complaint is enough to shut

down a trial account, or even a subscribed one, if the

submitted email bears the hallmarks of spam, with no

valid disclaimer.
Runbox initially allows legitimate, double opt-in

Internet marketing mailings. However, such email MUST

include full disclaimers and numerous complaints will

still get accounts shut down.
Runbox manually reviews all account registrations

continuously, and we suspend any account that look

suspicious as a preventive measure.
Runbox does not provide “Challenge-Response” anti-spam

filtering, because it isn’t particularly effective, it

misplaces the burden of spam management on the sender

(which is often not the spammer due to forged messages),

and several other problems. See for instance this

article for more information: Challenge-Response Anti-

Spam Systems Considered Harmful.

Whos Is U S P S Mailing System

The United States Postal Service (USPS), (also known as

the Post Office, U.S. Mail, or Postal Service), is an

independent agency of the United States government

responsible for providing postal service in the United

States. It is one of the few government agencies

explicitly authorized by the United States Constitution.

The U.S. Mail traces its roots to 1775 during the Second

Continental Congress, where Benjamin Franklin was

appointed the first postmaster general. The Post Office

Department was created in 1792 from Franklin's

operation, elevated to a cabinet-level department in

1872, and transformed in 1971 into the U.S. Postal

Service as an agency of the U.S. government.

The USPS as of February 2015 has 617,254 active

employees and operated 211,264 vehicles in 2014. The

USPS is the operator of the largest civilian vehicle

fleet in the world.The USPS is legally obligated to

serve all Americans, regardless of geography, at uniform

price and quality. The USPS has exclusive access to

letter boxes marked "U.S. Mail" and personal letterboxes

in the United States, but still competes against private

package delivery services, such as the United Parcel

Service (UPS) and has part use with FedEx Express.

Since the early 1980s, many of the direct tax subsidies

to the Post Office (with the exception of subsidies for

costs associated with the disabled and overseas voters)

have been reduced or eliminated in favor of indirect

subsidies, in addition to the advantages associated with

a government-enforced monopoly on the delivery of

first-class mail.Since the 2006 all-time peak mail

volume,after which Congress passed the Postal

Accountability and Enhancement Act, (which mandated

$5.5 billion per year to be paid into an account to

fully prefund employee retirement health benefits, a

requirement exceeding that of other government and

private organizations , revenue dropped sharply due

to recession-influenceddeclining mail volume,

prompting the postal service to look to other sources of

revenue while cutting costs to reduce its budget

deficit. The USPS lost $5.5 billion in fiscal year

2014 and $5.1 billion in 2015, and its revenue was $67.8

billion in 2014 and $68.9 billion in 2015.

20th century[edit]
The advent of Rural Free Delivery (RFD) in the U.S. in

1896, and the inauguration of a domestic parcel post

service by Postmaster General Frank H. Hitchcock in

1913, greatly increased the volume of mail shipped

nationwide, and motivated the development of more

efficient postal transportation systems.[28] Many rural

customers took advantage of inexpensive Parcel Post

rates to order goods and products from businesses

located hundreds of miles away in distant cities for

delivery by mail.[29] From the 1910s to the 1960s, many

college students and others used parcel post to mail

home dirty laundry, as doing so was less expensive than

washing the clothes themselves.[30]

After four-year-old Charlotte May Pierstorff was mailed

from her parents to her grandparents in Idaho in 1914,

mailing of people was prohibited.[29] In 1917, the Post

Office imposed a maximum daily mailable limit of two

hundred pounds per customer per day after a business

entrepreneur, W.H. Coltharp, used inexpensive parcel-

post rates to ship more than eighty thousand masonry

bricks some four hundred seven miles via horse-drawn

wagon and train for the construction of a bank building

in Vernal, Utah.[31][32]

The advent of parcel post also led to the growth of Mail

order businesses that substantially increased rural

access to modern goods over what was typically stocked

in local general stores.
