Kmail again

[Orjan Sinclair]

I am using KMail (in Kontact) and really like it. But there is an 
irritating "problem" I have;
I use around 5 different pop-accounts due to various business and 
organisational reasons. When I do a reply on a mail I want to be sure 
that the "reply-to" address is the one connected to the account the mail 
arrived to.
This seems a bit tricky. On pop and smtp-accounts I don't find this but 
only on "Identities". Do I have to set up x number of identities rather 
than pop- or smtp accounts to achiev this functionality?
