RE: Major E-mail Delivery for FTC DNCR Launch

You will want to make sure your email and sending server avoid the appearance of evil, I.e. Forward and reverse records match, valid MX for the sending domain, sent from a real address, not an HTML email, etc. -----Original Message----- From: Andy Dills [mailto:andy@xecu.net] Sent: Wednesday, June 25, 2003 3:17 PM To: Callahan, Richard M, SOLGV Cc: nanog(a)nanog.org Subject: Re: Major E-mail Delivery for FTC DNCR Launch On Wed, 25 Jun 2003, Callahan, Richard M, SOLGV wrote: > > Good Afternoon > and forgive the new guy if I break any rules or conventions. > > I work for AT&T Government Solutions and we are about to launch the Do > Not Call Registry for the Federal Trade Commission.

Posting to the news.admin.net-abuse.email newsgroup would definitely be a good idea. The worst bunch to deal with is the SPEWS crew, and that's their only contact method. However, you don't really run too much risk; we provide co-location services for an organization that does large opt-in only mailings (financial services newsletters, catalogs, etc). They get almost NO complaints, which is absolutely amazing considering the amount of mail they send out. The complaints they do get are swiftly met with proof of opt-in, which you guys will obviously have. They haven't had problems with blacklists, and have been in business for several years. If you were to provide evidence of the request in the email that you send out, and considering that this is basically an anti-phone-spam service, I'm willing to wager your complaint rate will be very minimal, especially if the email arrives quickly after the request for processing.

Latency generator?
by Temkin, David 25 Jun '03

25 Jun '03

Does anyone know of any free, cheap, or potentially rentable latency generators? Ideally I'd like something that just sits between two ethernet devices to induce layer 2/3 latency in traffic, but am open to any options...

Thanks for all the replies. I was not sure how to tackle the origin problem, so I figured I'd leave it wide open. Both origin as seen by the network, prima facia, and orgin as traced through proxies etc. are useful. Please send along either, but maybe a discalimer saying which would be useful.

It's a standard part of FreeBSD and may be in other BSDs. It's very configurable to generate delays, congestion like behavior and such. NAME dummynet - traffic shaper, bandwidth manager and delay emulator DESCRIPTION dummynet is a system facility that permits the control of traffic going through the various network interfaces, by applying bandwidth and queue size limitations, implementing different scheduling and queue management policies, and emulating delays and losses. -- R.

Sean, of the scans I get and have seen.. 60% APNIC region Most noteably- Taiwan, China, and Korea (north) 20% RIPE Most noteable- Former Soviet Block nations then Scandanavian countries... 20% ARIN/LACNIC This is a rough estimate from the last 3 weeks... I guess you may be after this kind of fact: When I blocked HINET (Taiwan based-- has a single /16 to my knowledge) I cut scans/probes by 20%....

I've searched the archives, and didn't see anything current. I am looking for a small, cheap, simply device, that can measure temp and be polled via SNMP. POE would be a plus.

Network Solutions woes

Does anyone out there from netsol, or anyone who knows someone from netsol, actually remember this little thing we used to call a "role contact"? If so could they please contact me. I honestly cannot find anyone at netsol who knows what one is, their website interface destroys existing role contacts and replaces them with "ContactLastName, ContactFirstName", and their email template system spits out "incorrect version for domain template" responses even though it is clearly a contact template and not a domain template. -- Richard A Steenbergen <ras(a)e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
