Brauche Hilfe mit ner Exeption

[wallkecks]

Mein Programm beendet sich nach unterschiedlichen Zeitabständen und wirft folgende Exeption:

Exception in thread "Timer-0" java.lang.RuntimeException: java.net.ConnectExcept
ion: Connection refused: connect
at tellonmail$1.run(tellonmail.java:139)
at java.util.TimerThread.mainLoop(Timer.java:512)
at java.util.TimerThread.run(Timer.java:462)

Und ich hab keine Ahnung woran es liegen könnte hab schon ein haufen try/catch rein gemacht um den Fehler näher zu lokalisieren aber ohne Erfolg. Vieleicht hat ja einer von euch eine Idee, danke schon mal im vorraus.

    		timer.schedule(new TimerTask(){

Vielleicht hilft dir das hier, aber selbst hatte ich mit der Ex. auch nichts zu tun.
Eine kleine Erklärung steht da ja immerhin
