Non pop3 mail accounts or lotus at XDA IIS

[RELOAD]

My company using non pop3 mail account and normally we are using the lotus notes for mails. At xda IIS or any other xda's i didn't find any way to get these mails to my XDA except mNotes , but at the mNotes you have syncronize the XDA with your pc&lotus. Reason of i am getting an XDA is get rid of carrying laptop etc... But i cant get my mails . At some blackberry's i see the lotus program can get the mails without syncronize with the pc. Is there any program or anyway to do this at XDA IIS or any other XDA ?
