I need someone to do two things:

1 look into the SMTP running on linux and work out way I have high reject rate for emails generated by kayako esupport. I think is a wrong DNS entry or something like that.
2 install me antispan and antivirus software for the SMTP. The software need to be self updating.

I can do this. Pm me if interested.
