This week's book giveaway is in the Other Open Source APIs forum. We're giving away four copies of Storm Applied and have Sean Allen, Peter Pathirana & Matthew Jankowski on-line! See this thread for details.
Hello, I'm having an issue with JavaMail, that is kind of frustrating. i'm currently modifying a program that uses the javamail api to send errors and traces to clients if the program fails. The problem is that sometimes the emails don't send. The frustrating part is that some errors are emailed and some are not, even out of the same class, so this problem would seem to not be relegated to just a singular class.
I've enabled debugging and am not seeing anything relevant. My gut tells me that it has something to do with the subject(thought, I couldn't tell you what.)
I have debugged the code and everything is being submitted properly. The email just doesn't send.
Has anybody had this issue before?
Here's the debug trace...

Also, if I hard code a "String" in to the subject variable, the email will send. Is there some kind of restriction on the subject or something?
If e-mails are received from the server unreliably and no errors are occurring when you send them to the server via JavaMail, then I would say your server is having problems. Have you discussed this with the server administrator?
Also, if I hard code a "String" in to the subject variable, the email will send.
Does this change make the e-mails be received 100% reliably, or is this just based on a small number of tests?
Originally posted by Rob Prime: Have you tried checking that exception stack trace? It's quite clear why it fails.
I got sucked in at first and posted that too. But the stack trace shown there is actually the body of the e-mail. As B said:

Thanks for you reply's. I've only run through a small number of tests. But it would seem that when I hard code a subject in a email that won't send with a subject variable. The email will send. Again, to me it seems as if there is some kind of limitation. My subjects are a bit wordy, I have not checked with my admin, but I wanted to cover my bases with API first.
