For compiling look at the beginning of mail-filter-plugin.c
For using add it to mail_plugins and:
plugin {
mail_filter_executable = /path/to/your/script.sh
}
A script could be for example (totally insecure and broken):
#!/bin/sh
sed s/Hello/Hi/ > /tmp/foo
cat /tmp/foo
rm /tmp/foo
Unfortunately you can't both read stdin and write to stdout at the same time
because of some internal Dovecot problems with it. So you'll have to write it
to a temp file and then output that after the entire input is read.
