[Sqlgrey-users] sqlgrey fails when configured with multiple machines

[Alex <mys...@gm...>]

Hi,

I'm using sqlgrey with postfix on three servers, configured using the
DBCLUSTER layout as defined in the README. However, when one machine goes
down, all three fail, with the following postfix message:

Jun 30 06:14:00 mail03 postfix/smtpd[32601]: NOQUEUE: reject: RCPT from
bmail.bridgemailsystem.com[66.206.172.149]: 451 4.3.5 Server configuration
problem; from=<mar...@lo...> to=<Rya...@ex...>
proto=ESMTP helo=<bmail.bridgemailsystem.com>

Isn't it supposed to continue running on the remaining systems when one of
them becomes disconnected?

This is my sqlgrey.conf config on one of the slave machines:

loglevel = 3
log_override = whitelist:1,grey:3,spam:2
reconnect_delay = 5
db_type = mysql
db_name = sqlgrey
db_host = ns1.example.com
db_port = default
db_user = sqlgrey
db_pass = mypass
db_cleanup_hostname=ns1.example.com
db_cleandelay = 1800
clean_method = sync
db_cluster = on
read_hosts=localhost,mail02.example.com,mail03.example.com,
mail01.example.com
prepend = 1
admin_mail = my...@me...

Any ideas greatly appreciated.
Thanks,
Alex
