Currently you can't. I was a bit lazy in implementing this code not to preserve permissions. The idea would be anyway that you could make /var/mail/attachments 02770 and e.g. group=mail. Then set mail_access_groups=mail to Dovecot. Now the code should have created new directories under that with the same permissions and the files as 0660, but looks like it doesn't. The code is in src/lib-fs/fs-posix.c if you want to fix it yourself. You could as a workaround simply change all 0600 -> 0660 and 0700 -> 0770 and I guess it would work.
