Sad to say, but it sounds like Magic jack do not know what a mail client is. Not a good starting point hey.

So in the interests of keeping is simply. Do they send a normally formed email with a sound file attachment (something ALL mail clients and web sites would be able to receive). Or are they sending some sort of non standard (read non standards complaint rubbish) email that only special mail programs can read.

Do you not get the mail, or are you unable to listen to the attached sound file?

Currently I am not receiving any files from them.

In the past I received their files on a different Magic Jack with a different phone number. When I purchased a second one that attached to my router and had a second phone number, I discovered both could not send to the same email address. So I had the new unit go to a work email.

Their file is a normal email with a sound file attached. I believe it had a ".wav" extension.

Now I'm retired, no longer have access to the old work email and use my account through my ISP. I contacted Magic Jack to move voice mail to this account because I confirmed from a contact that they left me a message on voice mail and I did not get it. Upon my complaint Magic Jack people said messages were already going there. I told them I have never had messages from the new device. That is when they came up with their message about "the server not working with "your" client."

I taught computer science before retiring and Cicso Networking was part of my work. I also thought their answer was not appropriate. Closing my email account and moving everything to gmail or yahoo would be so simple for them but a gigantic mess for me. Trying to remember everyone in he world that I have established email relationships is very difficult to even think about much less do.

I wanted to bounce this your direction to see if you were aware of any other users that have had problems receiving Magic Jack voice mail or any logical reasons for such a problem to happen.

Magic Jack cold possibly do some further testing on their end, I'm trying to build a better case to present to them. Their older unit was able to send emails to my account years ago at bellsouth. I changed from the phone company to cable Time Warner now Spectrum.

Your company is large enough to have many customers using Magic Jack so this email problem should have already been seen by them before my request.

while it is accepted that Thunderbird has millions of users (around 10 I think) there is no "company. It is a volunteer run project under the general auspices of the Mozilla foundation. SO shall we say some thing are in short supply.

Having said that I have been around these support forums for some five years an you are the first I have ever heard of mention magic jack. So much so that I had to google them to have any clue what you were on about.

Personally I think the response you got would do a 6th grader proud. Not so much a professional support person. perhaps they could explain why any email system anywhere on the planet would not be able to manage an email with an attached wav file. Although a wav file is so old school. I would have expected a more up to date sound file format as wav is not compressed in any way they can become to large for email quite quickly.

My guess is they are alluding to the message size when they talk about some "may not be able to translate or accept messages from our servers" Roadrunner impose a 20Mb limit on message size, Gmail is larger as 25Mb. (50mb receiving)

These limits are a little misleading, as a file increases in size by about a third when it is mime encoded to attach to an email. so the reality is anything over about 12mb may fall over the limit.

Depending on sampling rates wav file can vary between 5 and 34mb per minute. so messages may well get beyond the limits set by roadrunner. It all depends on the sampling rate.

Now if these folk used MP3 then sizes would tumble. Reference http://www.audiomountain.com/tech/audio-file-size.html The use of WAV actually indicated developers which no knowledge of anything but Microsoft.net wav is the native windows audio file format dating back to the mid 1980s and like bitmap is simple but space hungry.

I would suggest you create a gmail account, or even a GMX one and get those addresses tested by these people. My guess is you will have no trouble with gmail as they have such a large incoming message size. Then simply add the gmail account to Thunderbird as another mail account. There is no need for that account to be used for anything or by anyone but Magic Jack. You can continue to use your road runner account for folks that actually understand email and the need to compress data. (although they are getting less all the time)
