I´m running amavis on the mailserver and need to change the permission,
so that the amavis user can run sa-learn on the folder SPAM to update
its bayes.db.
Im  putting not recognized SPAM to that folder.
Amavis is running through a cronjob sa-learn on the SPAM folder and
though update the bayes database.

The bayes database is in the amavis home-Folder: /var/amavis/.spamassassin/
with permission 600; user: amavis, group: amavis.


amavis is in the group mail
/etc/group:
mail::12:mail,cyrus,postfix,amavis

the cyrus imap folders are set to following user and group:
user: amavis
group: mail

Well i could run:
sa-learn --dbpath  /var/amavis/.spamassassin/ --spam
/var/spool/imap/xxx/user/xxx/SPAM/*.

Is it a security risk to set the Cyrus-Imap folders permission to 650 ?
