Hi
I'm seeing multple error messages like this in my Postfix configuration: "warning: psc_dnsbl_request: connect to private/dnsblog service: Resource temporarily unavailable" I also see from debugging with the "-v" command that not all blacklists are checked. I have found the error comes from this part of postscreen_dnsbl.c: if ((fd = LOCAL_CONNECT(psc_dnsbl_service, NON_BLOCKING, 1)) < 0) { msg_warn("%s: connect to %s service: %m", myname, psc_dnsbl_service); continue; } Appeantly the LOCAL_CONNECT is using unix_connect.c and opens a socket connection. So why do I get those messages and can't I open a socket connection to private/dnsblog? # cat /proc/sys/fs/file-max 203818 # postconf -d | grep mail_version mail_version = 2.9.6 Kind regards Laurens Van Acker
