And here is simple config based on what we use to expose mailman archives. It
should work, but as I removed settings there is small risk of mistake.
You need /srv/dovecot/anonymous directory with mail, control and index
directories. control and index need to be writable for vmail.
Then we symlink /var/lib/mailman/archives/private/dovecot.mbox/dovecot.mbox as
/srv/dovecot/anonymous/mail/dovecot
dovecot.mbox should not be, as this is read-only archive.
## dovecot.conf
auth_mechanisms = anonymous
# index and control need to be writable
mail_home = /srv/dovecot/%Ln
mail_location = mbox:%h/mail:INDEX=%h/index:CONTROL=%h/control
passdb {
args = /etc/dovecot/anon.passwd
driver = passwd-file
}
userdb {
args = /etc/dovecot/anon.passwd
driver = passwd-file
}
## anon.passwd
anonymous:{PLAIN}:vmail:vmail::/srv/dovecot/anonymous::nopassword=y
