I installed sendmail for use it with Kmail. Now Kmail sends e-mail but really it does not it. I am thinking that localhost ip is not right in Network Preferences. My network is with a modem-router (gateway 192.168.1.1) and localhost ip 127.0.0.1 as Kubuntu default is. What must i do for Kmail use sendmail and really sends e-mails?? Thank you.
