No, sorry - to much spannish(?) for me... :-)

But the Horde-project is very good. You could expand it with postit-notes, memos, calender, ToDo etc.

One other thing, why pop3? Imap is the better one. If you need offline-access then just mark the folders as "offline folders" in the mail-clients - remember harddisk-space is cheap compared to lost mail for users...
