a newsletter of our customers is marked as spam.
Stock spam image part 'Content-Type' found (8 spc) 1.6
Header has extraneous Content-type:...type= entry 1.0
Email has a inline gif 1.4
what means stock spam image?
what means inline gif?
is a jpg better than a gif?
whats the reason for the header ? : - ;
