Cant send email out again, tiuuuu

I really hate learning new things. Especially when i dont really have much time on hand. The O2 Zinc's Windows Mobile operating system is driving me nuts. I'm actually trying to set up the email accounts. I managed to send mail out for the whole the day, now, i can receive but not send out again, tiu. I cant check cos my other phones here cant send email. I suspect it's Maxis' problem, but cant verify. Geee.... when's my N73 coming back???? Getting tulan jorrr. Gonna goi fark the fler again tomorrow.
