I tried to set up Postfix (2.6.6) on a Centos6 system (yes, I've filed a bug for them to bump to something 2.8.x-ish)... as:
Dec 1 20:26:05 localhost postfix/smtpd[7743]: warning: connect to Milter service unix:/var/spool/MIMEDefang/mimedefang.sock: Permission denied # ls -ld /var/spool/MIMEDefang /var/spool/MIMEDefang/mimedefang.sock drwxr-x---. 3 defang defang 4096 Nov 18 18:48 /var/spool/MIMEDefang srwxr-x---. 1 defang defang 0 Nov 18 18:48 /var/spool/MIMEDefang/mimedefang.sock # the permissions on the socket itself are dubious (I'm thinking that 0660 would be more appropriate), but even after changing those it still fails. This was after doing: # usermod -a -G defang postfix so it would have group permissions to the directory and socket, but it looks like smtpd sheds its other gid's early on. My main.cf file contains: smtpd_milters = unix:/var/spool/MIMEDefang/mimedefang.sock milter_default_action = tempfail milter_protocol = 6 Would it make sense to add a parameter of additional gid's that you want smtpd to retain? Also, what about having a MIMEDEFANG_README file since the MILTER_README doesn't cover the specifics of interfacing to Mimedefang? Thanks, -Philip
