how to alter (filter) the subject of email (or its body) ?

[Michael REMY]

hi !

here what i need to do :

An employee write and send an email where the word 'goldorak' appears in the subject of the emai. I wish the output mail will be alter by replacing the word 'goldorak' by the word '****'.

is there any an option to do that for the subject ?

and for the body of the mail ?

in other word, i need a php str_replace function filter running on the output mail !

any idea of how to that ?

for incoming mail, you can use the postfix_header_checks file to do that trick, or the amavis configuration file. But to outside mails i have no idea.
