Hi List,I have implemented alterMIME for adding a disclaimer and X-Header to outgoing email.
I have written a script like described here: http://www.postfix.org/FILTER_README.html#simple_filter
It works fine so far, BUT if I try to add a disclaimer and the X-Header for LOCAL generated email I run into a problem with "Too many hops" and I understand why, but I have no solution for that.
When I configure in master.cf: pickup unix n - n 60 1 pickup -o content_filter=altermime:the "Too many hops" problem occurs, because the alterMIME shell script insert the email again and again, because the sendmail.postfix binary give up the email to pickup.
What can I do, to solve this situation? Hope of inspiration from the list... thank you! Klaus.p.s. My complete implementation of the alterMIME was dokumented here (sorry, only in German, but the configuration coammands speaks for itself):
