Why doesn't JavaMail work, but PHP mailer does?

I am trying to use JavaMail to send emails from my webserver. I've plugged in the host and the addresses are valid, but I am getting 550 errors. I've searched and found that I should change a setting on my mail server to allow relays from my webserver. However, we have a PHP mailer working on our webserver now, so presumably that relay is already in there. Why does the PHP work but the JavaMail doesn't?

Can you turn on session debugging and post the protocol trace that shows the failure?
The error codes alone are not enough, you usually need to look at the message included
with the error code.
Also, have you found the JavaMail FAQ?

Thunderbird works, but Apple Mail does not...

My issue is this:
Mozilla Thunderbird works great with my current POP account. Thunderbird can both receive and send messages--no problem.
Apple Mail cannot receive messages, but it can send them.
All the account settings are exactly the same. The only difference I can find is that in Thunderbird's Security Settings (under Server Settings in Account Settings) you have the ability to check "TLS, if available".
Anyone have any ideas why Mail can't receive messages?
I love the new Apple Mail and really want to use it.

Why doesn't siri work away from home

why doesn't siri work way from home

It does for me. But it requires an Internet connection, so if you don't have mobile data turned on or your account isn't provisioned for it or you are out of range of a cell tower Siri can't talk to the servers.

I recently bought a lightning to 30 pin adapter for my new iPad so that I could continue to use my 30 pin to VGA cord, but when I plug the VGA cord into it it says it is not supported. They are all apple products, so why doesn't it work?

If it is a lightning to 30 pin adaptor, and you have a 7th Generation Nano it has to fit the Nano.
This is lightning to 30 pin adapter: http://www.bestbuy.com/site/Apple%26%23174%3B---Lightning-to-30-Pin-Adapter/6651 936.p?id=1218803450821&skuId=6651936#tab=overview
Is this what you bought?
You need to contact Sony and see if they model you have is compatible with the docking adapter. It may not be.

Iphone 3g - why doesn't it work?

I purchased a new pair of Nike running shoes excited to link up the sensor and get started using with my iphone 3G. However, I find out the Nike Plus only works with an iphone 3GS. I'm now going to have to return the Nike Sensor for a refund instead of having to upgrade to another Iphone model. Is there anyway around this? Why doesn't it work with the Iphone 3G? What makes the operating system in the 3GS different so it works?

As evidence too there is a hack which gets it working as well:

Why doesn't Nike+ work with the 1st Gen Ipod touch with 2.1 software?

Why doesn't Nike+ work with the 1st Gen Ipod Touch with 2.1 software?

The second gen iPod Touch has firmware version 2.1.1(5F138) whereas the 1st Gen only allows 2.1 (5F137). Don't know if that has anything to do with it, but it's likely.
Why doesn't Apple allow those with the Nike+iPod sports kit to use their external sensor on the 1st Gen iPod Touch?!?! I can't see why the sensor would be incompatible with the right firmware upgrade!!

Why doesn't flash work during panorama pictures

HI..
Try troubleshooting the Flash plugin ..
Quit Safari.
Open System Preferences > Flash Player then select the Storage tab. Click: Delete All
Now uninstall the Flash plugin then reinstall new > Troubleshoot Flash Player | Mac OS
Very important to uninstall the currently installed Flash plugin before reinstalling.
Launch Safari From your Safari menu bar click Safari > Empty Cache
Now try a video.
BTW... if you have the ClickToFlash extension installed, that can prevent Flash based video from streaming. It can also be installed as a plugin in /Library/Internet-Plug-Ins.
And check to see if Safari is running in 32 bit mode. Right or control click the Safari icon in your Applications folder then click Get Info. If the box next to: Open in 32 bit mode is selected, deselect, quit then relaunch Safari.

}this program create a GUI containing a "add ball" button to creat a ball and make it bounce inside the window. ( this seems to be stupid example but it is just an example of why we should use Thread for the purpose ).
Note: in the move() method, if i use canvas.repaint() then the ball is not redrawn after each movement. but if i use canvas.paint(canvas.getGraphics()) then everythings seem to be OK.
Another question: Still the above programe, but If I create the ball and let it bounce in a separate thread, then canvas.repaint() in the move method work OK.
Any one can tell me why? Thanks alot !!!

I don't know why the one method works. Based on my Swing knowledge neither method should work. Did you notice that the JButton wasn't repainted until after the ball stopped bouncing. That is because of the following code:
for (int i = 1; i <= 1000; i++)
    b.move();
    Thread.sleep(5);
}This code is attempting to move the ball and then sleep for 5 milliseconds. The problem with this code is that you are telling the Event Thread to sleep. Normally painting events are added to the end of the Event Thread to allow for multiple painting requests to be combined into one for painting efficiency. When you tell the Thread to sleep then the GUI doesn't get a chance to repaint itself.
More details about the EventThread can be found in the Swing tutorial:
http://java.sun.com/docs/books/tutorial/uiswing/misc/threads.html
This explains why the button isn't repainted, but it doesn't explain why the ball bounces. I don't know the answer to this for sure, but I do know that there is a method called paintImmediately(...) which causes the painting to be performed immediately without being added to the end of the Event Thread. This means the painting can be done before the Thread sleeps. Maybe the canvas.paint(....) is somehow invoking this method.
When you click on the button this code is executed in the EvWell in Swing, all GUI painting is done on the Event Thread

Why doesn't tmobile work at ORD?

Since upgrading to OS X 10.7.3, logging onto wifi networks has been much more difficult. At ORD, at least in the United Club, it is impossible using the T-Mobile network. Whenever I connect to the tmobile network, it opens the new (supposedly-quasi-automatic) wifi login screen. But it gets stuck there forever, with an indication that it is trying to connect to an apple URL. Why? Is there away around this? Here's the screen I get (forever):

alright, you guys, forget about what i just said... i know why it's not working, it is a file that is not as a quadratic picture but one that is just cut out of a quadratic picture. so it's probably that's why it is not working....
so let's take this thing to a different level:
how can i get things that i cut out from editors like gimp and made a jpeg file out of it get into imovie when they are not quadratic?
My idea is to make a video and add in the foreground some little pictures. something like a logo that i can't make with the writing software of imovie. So hoy can i add such a thing or is it even possible?
