Hi there,
If I turn off chroot for smpt then postfix cannot access the milter using the fully qualified path name and if I turn on chroot, then postfix can access the socket using the chrooted value. Server is Debian 6 running with Postfix 2.9.3-2.1~bpo60+1. Values running smpd in default chroot environment, and smtp chroots to /var/spool/postfix. smtpd_milters = unix:/spamass/spamass.sock Values running smtp in non-chroot environment, smtpd_milters = unix:/var/spool/postfix/spamass/spamass.sock Error message is this: Nov 12 13:37:08 lt postfix/smtpd[30776]: warning: connect to Milter service unix:/var/spool/postfix/spamass/spamass.sock: No such file or directory Files and directories were present and rw for postfix user, # ls -ld /var/spool/postfix/spamass/spamass.sock srw-rw---- 1 postfix postfix 0 Nov 11 15:08 /var/spool/postfix/spamass/spamass.sock # ls -ld /var/spool/postfix/spamass/ drwxr-xr-x 2 spamass-milter root 1024 Nov 11 15:08 /var/spool/postfix/spamass/ The milter works perfectly well and responded correctly, and the milter is spamass-milter. I'd be very grateful for some tips. Thanks, Si
