Postmaster Resources

This post is as much to help me remember as it is to help other people.

Below is a list (not comprehensive) of the postmaster resource pages for some of the major email providers.

Microsoft / Outlook https://postmaster.outlook.com
Google https://postmaster.google.com/
Yahoohttps://help.yahoo.com/kb/postmaster
Comcasthttps://postmaster.comcast.net/
AOL https://postmaster.aol.com/

On these sites you can get information about how the provider handles spam, feedback loops, blacklists, whitelists, etc.

Very useful for those managing mailing list servers.

Your ISP’s DHCP does not function properly

As part of my migration to the cloud, I terminated the Comcast Business internet service and switched to Xfinity internet.

When I initially signed up for the Xfinity service, I got their cable modem / router / wifi appliance. My plan was to get my own cable modem eventually because Xfinity charges $13 / month to lease the appliance.

I was at Best Buy and saw that cable modems weren’t expensive, so I decided to purchase a mid-level model (Netgear CM600) so I could save the lease fee. The CM600 would pay for itself in about 8 months.

It took a while to get setup … and there were a few false starts, but eventually I got it working connected directly to my MacBook.

I ran into a problem when I switched the CM600 over to my ASUS RT-5300 wifi router.

I kept getting the message “Your ISP’s DHCP does not function properly” on the ASUS network map page.

Cycling Sunglasses

One of the things I’ve struggled with since I started seriously cycling was eyewear.

I normally wear glasses … but, occasionally, wear contact lenses.

The problem is, with contact lenses, I’m far sighted … but can’t read anything up close (specifically maps, cue sheets, and my bike computer to a certain extent). I also find it hard to drive with contacts in (The dash board & GPS display are just out of the clearly visible range). If I wore reader glasses (+1.5), I was able to see stuff close up.

Filtering mailing lists in Gmail

With my recent migration of servers from my basement to Amazon cloud servers, I had to rework how my email filtering was setup.

One of the challenges was how to handle the numerous mailing lists I participate in. Especially since I’m the list administrator for many of them.

After a bit of research, and experimentation, I found a pretty good formula for handling the filtering.

Wahoo Headwind

The Wahoo Headwind is a ‘smart’ fan specifically designed for cycling.

When I first heard about this product, I was quite dubious. First, and foremost, it’s expensive. $250 for a fan is pretty high. Also, for some reason, my initial though twas that they were trying to reproduce the experience of a headwind while cycling.

Well, cost aside, most of the reviews of the fan I saw were pretty positive. With the holidays upon us, this is what I decided I wanted

4iiii Viiva Heart Rate monitor revisited

Some time ago I posted about my general dissatisfaction with the 4iiii Viiva heart rate monitor.

In a nutshell, in addition to being a ANT+ and Bluetooth Low Energy (BTLE) heart rate monitor, it also acts as a bridge between ANT+ devices that don’t offer BTLE functionality. In my original review of the Viiva, I complained because few software offerings provided support for it and the data is sent to apps wasn’t accurate.

Well, I need to revise my opinion of the Viiva … it has gained adoption and now appears to be quite useful.

Those who use training programs (such as Zwift) with Apple TV have already learned that the Apple TV only supports 3 total BTLE devices connected. One of those devices slots is already taken by the remote control. That leaves only 2 more slots.

If you’re using a training program, you’ll need at least 3 devices connected (possibly more) …

Garmin RTL-510 Radar

Review of the Garmin Varia RTL-510 Radar

Standard disclaimer:

Being into technology, I’ve accumulated a fair bit of bike tech also.  As such, I’m going to try doing thumbnail reviews of some of the bike tech that I current, or used to, use.

These aren’t going to be super technical reviews.  For that kind of thing I suggest you head over to
DCRainmaker‘s blog or GPLama‘s YouTube channel.

These are going to be my impressions of the product … what I like, what I don’t like, what could be better, and some things that should be left just the way they are.

All the items I’m going to review have been purchased outright by me and I don’t get any compensation for the reviews (unless I provide an Amazon link, in which case I get a small commission).

A few years ago I decided I could try bike commuting to work. The office I work in has a bike rack and (lucky for my co-workers) a locker room with showers.

I figured I could leave earlier than I normally would, ride the 20 miles to the office, lock my bike up, shower, and start work about an hour after I normally would. I would leave a change of clothes, toiletries, and fresh cycling kit for the ride home.

Poor Customer Service

Once again I’m experiencing some very poor customer service … and, at least in one case, it really surprises me that I’m experiencing it.

So there are two major issues I’m experiencing …

  • A major internet provider email service. My newly spun up Amazon LIghtsail instance is unable to deliver mail to their customers.
  • A relatively small fitness device manufacturer isn’t providing timely support for their product.

The first issue is with the major internet provider (who shall remain nameless, but the company name is often abbreviated to three letters.

I’m in the process of moving my mailing list server to an Amazon LIghtsail instance … but when I send mail to this ISP’s servers, it gets rejected with an error that indicates an email to contact.

About a month ago I encountered the error while testing and send a message to the address indicated. A week after my contact they responded saying that the block had been removed.

Unfortunately, in some final testing before my planned migration (this coming weekend), I encountered the error again.

I thought it has been resolved, but apparently I was wrong.

The big issue is that it takes them a week to respond. So there’s very little chance of the issue getting resolved before this weekend. As a result, I have to postpone the migration. I would not be surprised if it takes more than a month to resolve the issue.

To be honest, I’m quite used to this kind of response from a major internet provider … they probably get slammed with this kind of request. Plus, I suspect, they really don’t care about small business that want to send mail to their customers.

The other issue is with a relatively small engineering company that makes a device that gates ANT+ signals to Bluetooth Low Energy (BTLE).

I purchased the device to make it easier to use Zwift with my Apple TV.

From the moment I got the device I’ve had problems. Their web site has no ‘support’ contact information. I tried filling out their ‘contact us’ page but got no reply. Finally I sent a message to the email address listed on their domain’s whois information and got a reply indicating they forwarded my message to someone else.

My first attempt to contact them was December 8th.

A few days later I got a response indicating they were aware of the problem and were working on a fix to their configuration app. They also asked if I would be interested in a replacement device to see if that fixed the problem. I responded that I would like to try a replacement and provided a shipping address. This response was sent on December 13th.

I finally got a response today indicating that they would like to get the device back for analysis and asking where I purchased it and the order number. I provided the requested information and they informed me that I would have to go back to the purchase place to get an exchange.

Sigh … more delays.

In the case of the internet provider, I’ve come to expect that level of customer service. In the cast of the engineering company, I’m quite surprised. They should be much more responsive to customer issues. Especially since they are catering to a niche market.

OK, today’s rant is over.
