My Sprint Treo 600 mail program works okay except it has a 3k limitation on email size which precludes most attachments from getting through. I have heard Snapper Mail and Aileron are good email programs however my IT administrator said that they would not work because I am running my email through our company network and directly to the PCS Business Connection running on my desktop and not off any Pop3 or IMAP protocol. Is that true? Do I have any options?
