All,
Some postings a while back led me to believe that I could specify multiple hosts for the -d option of spamc. I understood that it would operate basically on a fallback basis (not load balancing). However, I can't seem to get spamc to use more than one of the -d listings. I've tried:
/usr/bin/spamc -d 123.45.67.8 -d 127.0.0.1 /usr/bin/spamc -d 123.45.67.8 127.0.0.1
And switched the order around and fiddled with hostnames vs IP addresses, but no dice. I understand the man page to say that it will use fallback logic if the hostname resolves (via DNS query, right?) to more than one host... so why can't I give it those hosts directly?
TIA!
From http://spamassassin.apache.org/full/3.0.x/dist/doc/spamc.html
"-d host
In TCP/IP mode, connect to spamd server on given host (default: localhost).
If host resolves to multiple addresses, then spamc will fail-over to the other addresses, if the first one cannot be connected to"
You need to have a host that has multiple A records.
spamd.domain.com A 123.123.123.123 spamd.domain.com A 123.123.123.124 spamd.domain.com A 123.123.123.125
/usr/bin/spamc -d spamd.domain.com
If your DNS server sends the results back in a different order each time then it will not be a fallback but a round robin. You might be able to simply use /etc/host entries. I've never tried it as I use qmail which will not use the host file, so I always rely on DNS. Don't know if spamc will use the host file or not.
