This little freeware lets you config
max three email accounts, POP3, IMAP
or Hotmail (or Yahoo), ICQ, paging and a Newsgroup. Apparently all encrypted.
Tested it myself and it worked great.
You need to have a working connection
between your phone and your Palm before
you can assign your email accounts.
My guess is that they use their own site
as a link to whatever service you use.
Thats why you need a working connection.
