Re: handling spam from gmail.

• Andreas Born:

There exists one problem: at this stage of mail reception you have no body content nor header information on which a milter may perform deeper analysis, only envelope data.

I am not sure what you mean by "this stage of mail reception", or what software you are using that may be limited in such a particular manner, but generally speaking you are wrong.

For example: Postfix supports both before-queue filters and after-queue filters. Milter-regex[1] supports both multi-header and body checks. The milter protocol itself allows for both header and body manipulation.
