Hello list,
we are using dovecot-lmtp for delivery to virtual users, and vmm[1] to manage them.
One nice feature of vmm is that every virtual user has their own UID/GID on the UNIX filesystem. There is no passwd entry, so no shell login, but each user effectively has a home directory and can run commands in isolation and with lowered privileges.
This requires dovecot-lmtp because only the LMTP LDA runs with root rights and can drop privileges to become the specific user for which it is delivering mail.
We would now like to run SpamAssassin with the possibility of using the antispam plugin to enable virtual users to train their databases.
Do you have an idea how I could let dovecot-lmtp invoke spamc? Or an external command as a filter, to be run by the final user?
Thanks,
