Hi,

I'm using CoreBlog2 0.9b for Plone, and I get spammed with trackback pingin=
g. I've disable trackback in my entries (cannot add/hidden), but I'm still =
receiving mail notifications. So I dig a little and found a possible bug (a=
t least annoyance), in the tbping python script:
 =20
  1. the script first sends mail notification
  2. then tries to add the trackback

I would have expected: try *then* notify. More, while adding trackback, the=
 script isn't interrested into the return value of addTrackback2Entry(). As=
 a result, event if the trackback is closed/hidden (that is, not open), the=
 script won't be aware about this error (addTrackback2Entry() will return N=
one), and will return a tbping_result with error code ok.

FWIW, attached is my customized tbping script.

Hope it helps,

Cheers,

Seb
