In any case, it's likely that the delivery process looks in the user's

you've taken steps to prevent this.
I can confirm this. I think the reason is that dovecot changes to the
user's home directory so that it has a place to dump core. This causes
problem for my setup since I user per-user NFS mounts, so a delivery to an
internal mailing list caused hundreds of NFS automounts.
I patched this behaviour out, but there is probably a more elegant solution
(unset MAIL_STORAGE_SERVICE_FLAG_ENABLE_CORE_DUMPS? How?).
