That's legit.

It's also legit for private networks to not accept mail from dynamic IP
ranges.

nope. That approach is just "shoot em all, sort em later." The
"effectiveness" of it doesn't make it legit.

iow - since so much email is spam/uce, just delete them all.

That's disingenious and you know it. My spam filter can be thought as
the INS of my computer: just like people from countries where the most
illegal immigration come from don't get to be in the visa waiver
program, email from where most the spam comes from has to go through the
proper channels. The vast majority of the spam comes from dynamic IP
address ranges that are listed in the SBL's Exploit Blacklist. If you
happen to live in those places, and you want your email to be accepted
by my private network, you must go through the proper channels - your
ISP's smart host. Or stop being a skinflint and get a proper business
DSL connection that supports servers (or host your mailserver elsewhere,
a suitable VPS starts at a very good price).

Or are you suggesting it's feasable and worthwhile for 12 users to sort
through over 2500 pieces of spam to find on average 10 legitimate emails
a day each? Why should we spend hours filter by hand just to allow a
handful of geeks to run servers on a consumer dialup connection?

some reasons:

because the provider has proven to be unreliable.

If the provider has proven unreliable it is highly unlikely their dial
up service used as a server is going to be more so.

it turns out that my ISP was able to provide the connectivity
but didn't know much about keeping email (and usenet) servers
up and running.

because it is really to change email addresses.

I can change e-mail addresses on my ISPs server in a matter of
seconds. I log in, go to the proper URL, create and or delete
addresses. It doesn't take much longer than that.

When I first starting running my tiny email server, my ISP
didn't allow email name changes, never mind have multiple
email accounts.


[snip]
Yet, I do know of one person who insists on using his own server and
mail server on cable. Never have figured out why.

see above.

Nah, it's gotta be more than that.

it really is as simple as that in my case. My use of
of a home email server is classic geek.


His server is less reliable, he
moved to cable and although he claims it's static, the IP changes
every time he reboots.

My ISP's DHCP attempts to give out the same IP. My "dynamic IP"
changes only when the ISP needs to move folks to a new subnet
(or the DHCP burps bigtime). In the past 6 or 7 years, I might
have had 6 or 7 IP changes (and almost that many hostname changes,
highway1 to roadrunner to mediaone to attbi...)


He has to feed all his machines through one on
a different NIC so he can get away with using a server on the cable.

Yes, the cable is cheaper and faster than DSL. OTOH, I use web
hosting, I pay about $40 a month more than he does, I don't have to
service the equipment, I don't have to keep backups, I don't have to
do the many things the ISP does to deal with the whole wide world, and
my server is legal. Still I have firewalls, virus checkers, spam
bots, and the like.

Most of the spam originates in the US.

Your assumption regarding whether or not I'm being cheap is incorrect.

Your assumption that only business accounts can properly run servers is
incorrect.

But my assumption that 99.9% of mail directly from a dynamic IP address

just because one geek refuses to get a static IP address for their

visit the US, if you want your mail to be delivered to my users, you
must use an IP address which is not strongly identified with machines
running malware.

If you're not being cheap, what exactly are your reasons to send mail
directly from your dynamic IP address instead of ponying up for a VPS or
a static IP address?

Comcast cable is $70/month here. Verizon DSL is $40. I haven't noticed any
difference in speed, but then I'm not uploading much. Supposedly that's where
cable is greatly superior to ADSL.

I think it mainly depends on the provider as to which is superior. ADSL
(at least the flavour we have here) is IIRC, if you're within a suitable
distance limit of the phone exchange, is capable of up to 8Mbit/sec down
and at least 1Mbit/sec up. Of course, the telco only provides us with a
fraction of that!

Cable is also asymmetric, and I think the bandwidth you get depends
again on the provider.

However, once you get to the DSLAM or cable head-end, you've got
contention to worry about - a certain number of users will share a
certain amount of bandwidth. For here, if you pay extra for a business
account, you get backhaul shared with fewer users.

Then there's RADSL (rate adaptive ADSL), which is probably what they are
really using. I think in the DMT (discrete multi tone) linecode scheme,
the download part of your ADSL link uses the lower frequencies, and the
upload part uses the higher frequencies (the copper loop to the phone
exchange IIRC has about 1.1MHz or so of usable bandwidth, but don't
quote me on that!) The higher frequencies attenuate more than the lower
ones - so if you're a long way from the phone exchange, RADSL will tend
to lower your download speed if there's lots of signal degradation,
since that's what'll start to go first.

this has some logic. because you can reach more customers with lesser
bandwidth.

Cable is also asymmetric, and I think the bandwidth you get depends
again on the provider.

cable by itself or xDSL by itself is not asymetric. it is what you make out
of it. when using *A*DSL you go assymetric. when you use SDSL or G.HDSL you
have a symetric line. for cable it is only the rate that it is set.
besides: you (technically) can have ADSL with 512 up and down.

However, once you get to the DSLAM or cable head-end, you've got
contention to worry about - a certain number of users will share a
certain amount of bandwidth. For here, if you pay extra for a business
account, you get backhaul shared with fewer users.

same applies if your line goes direct into the POP of your ISP. at some
point you are on a shared network. it is all about the overbooking factor
and how your customers notice a delay.

I'm not sure if it is quite that high, but the figure is staggering.
Given a cable network with thousands of users, it only takes a few
infected machines, and or a few actual spammers to really tie things
up.

I've said it before, but not just the average user, but most are
absolutely clueless. They do not know how to, or care to bother
practice safe computing. They enable HTML e-mail instead of setting
it to plain text. They have their address books set to automatically
take any new addresses to which they send e-mail. They open
attachments as they know "their" friends would never send them a
virus. They have their systems set to automatically run macros. and
on and on and on... They do not use fire walls or virus checkers and
then when something happens they blame the operating system. Never
mind that had all the defaults been turned off they would have turned
them back on.

The spammers have discovered that the best way to get addresses now is
to infect the machine so it sends out the contents of their address
book. This has given them a whole new set of addresses that are never
put up on the net.

just because one geek refuses to get a static IP address for their
mail server. Just like if you come from North Korea, you need a visa to
visit the US, if you want your mail to be delivered to my users, you
must use an IP address which is not strongly identified with machines
running malware.

And the static IP for the mail server is easy to get. All you do is
use your ISPs mail service rather than creating your own server on a
dial up. Or sign up for one of the free ones.

directly from your dynamic IP address instead of ponying up for a VPS or
a static IP address?

It doesn't cost me a cent extra to use my IPSs mail server (static
IP), or in this case, my own (which is static) although the host is
located at the ISPs rather than here. It's much faster.

The point is there is no real reason for the end user to use dynamic
e-mail addressing.

I will make a prediction. It won't be long and ALL e-mail will have
to have a valid return address. There will be no more legal anonymous
addressing, or posting.

Even with the "do not call" list, I still receive more telemarketing
calls than spam. (political campaigns, special interest groups,
charities, religious organizations... they are by definition exempt
from that law)

Thing is, a reverse look up will show a valid IP so you are still for
all effective purposes using a static IP.
