Popcorn email client

Just downloaded the latest version of popcorn to see if it would stop trying to be the emailserver that I am trying to send to. (when it sends email it sends the command EHLO mail.domain.com if my mail server is mail.domain.com). This causes problems for pipex (unsuprisingly). However the latest versions are no longer freeware, but shareware in that you have to register it if you want to use multiple pop accounts. Thats a big shame as that is what I use popcorn for. So its back to the older 2001 version.
