Hello community!
The current documentation <http://www.postfix.org/FILTER_README.html> states: The "-o content_filter" line causes Postfix to add one content filter request record to each incoming mail message ... Q1: Is it still true you can not give a list of content filters which are processed one after the other? Q2: Assuming this is still true and content_filter does not take a list of filters, is there a better technique than creating a "wrapper script" to call the multiple filters one after the other? Background: I currently pipe my mail to spamassassin, but I also want to call a program adding a boilerplate for each outgoing mail (legal reason), and I think about a script which modifies incoming mails to strip html links to prevent my users clicking on them. These are three filters which should run on each mail. Bonus question: I can configure a content_filter for each service defined in master.cf, but there is also a parameter content_filter in main.cf. What does the latter refer to, and in which order are they processed? I'm confused ... Thank you!
