Hi
I migrated my dovecot server from Maildir to mdbox with saving attachments
to external files and enabled SIS a few days ago.
Everything works fine except one issue. I have both virtual and system
users. Dovecot saves attachments with mode 0600. So I catch such errors for
system users:
dovecot: lda(wasya): Error: fs-sis: Couldn't read hash file
/var/mail/attachments/2e/dc/hashes/2edc6009bc9b6ba38febb581df03986dcaf134d9:
Permission denied
I want to fix this issue by changing default file mode to 0660 via group
policy.
I found such feature in the changelog (v2.1.rc2 2012-01-06):
lib-fs: Added "mode" parameter to "posix" backend to specify
mode for
created files/dirs.
Unfortunately I can't find any information about this feature in the
dovecot documentation.
Can I use it to setup mode 0660 for attachments in the dovecot
configuration?

Thank you
