Is it otherwise a Maildir? If yes, you could base your code on the zlib plugin, or perhaps more easily you could use mail-filter plugin: http://dovecot.org/patches/2.0/mail-filter.tar.gz
are there any examples or how too online for mail-filter ?
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.
