Can Plesk work with Imail or Webtrends?

[CrossEye]

I am wondering if Plesk can work with Imail or Webtrends because I really think that both of them are the best in there fields right now. The best part of it all is that I have already paid for Imail and Webtrends and want to keep using them! So my question to you guys is can Plesk work with either Webtrends or Imail or both?

Thanks in advance for any help!
