ckeditor change generated output for paragraph element

[neciserv]

Our application uses ckeditor to generate user friendly email content to send email to clients. Email content is prepared by business people so they don't know any html at all.So I want ckeditor to add inline style to paragraphs(\[code\]<p>\[/code\] elements) such as \[code\]<p style="line-height:20px;">\[/code\] automatically instead of just generating \[code\]<p>\[/code\].Since the generated output is emailed I don't have any chance to use CSS file.I tried to wrap \[code\]<p>\[/code\] elements within \[code\]<table>\[/code\] but I couldn't change "line-height" property in that way, since email sites like gmail, yahoo have already their own styling for \[code\]<p>\[/code\] elements. I must use inline style for each \[code\]<p>\[/code\] element I think and I don't know how to achieve this.Can anybody help?Thanks
