Hi,

     [1] Does any one know how to configure mail settings on osclass mail server section? I tried many times to configure it
          but does not send emails. If i leave everything blank except for hostname=localhost it works.

          Hostname.................. default local host it works when everything else is blank.
          Mail from............?
          Name from..........?
          Server port.........?
          Username...........?
          Password----------?
          Encryption...........?
          SMTP SMTP authentication enabled..?
          POP Use POP before SMTP..............?

     [2] i would like to place arrow buttons on item listing page for use to navigate to  next or previous listing.
          e.g    <<------(go to previous listing)-----  [Current Listing page] ----(go to next listing)---->>
         Is is possible to do this?

1) use gmail account if it does not work for you.
2) I remember there exist some plugin for this.
