I can hand out around 90 of them, so if you want one, feel free to ask here or PM me.
There are 3 available webmail interfaces- SquirrelMail, UebiMiau and Roundcube. And of course there is the possibility of using a mail client like Outlook Express (messages are downloaded right into your computer so messages already received won't show up on the webmail).
