i'm a newbie to this forum (got a treo 650 yesterday). I've set up an IMAP maccount for my mail BUT i can't send from it. I get this 501 Syntax Error message. I'm with o2 in the UK and i've set up imap accounts before on a pda but never had this message. i'll call o2 support ( ) but if anyone here has an idea of what is causing the problem and how to solve it it would be much appreciated.
sorry if there's already been a long discussion on this topic - i did a search but couldn't find anything.
