include sent mails in thread

[hatsch]

hi all,
i just recently tried the beta service on mykolab.com and i must say,
i like it very much!
there is only one little thing i find annoying, which is that sent
mails are not included in the thread view. i've read somewhere that
this is because of the nature of IMAP folders, but from a user
perspective this is something one just expects.
is there any way to change kolab to that behaviour?

thanks for your respond
stefan
