I seem to recall @Mail not working well on Windows Mobile 2003, but I think
nPOP works fine on the latest version. If you want to view HTML mail, you have to edit nPOP.ini with these lines:
Code:
ViewApp="\Windows\iexplore"
ViewFileSuffix="htm"
Then you should be able to view it by going to File -> External Viewer.
I'm not entirely sure this will work, as when I got my new iPAQ I had to start using an IMAP server, so I can't use either of these programs, but I hope it helps!
