If I do: hosts = ${lookup mysql ..... }
and the query returns multiple hosts, I'd have this after expansion:
hosts = 127.0.0.1\n
192.168.1.1\n
192.168.1.2
replacing \n with a NL.
Exim will check to see if host (say 127.0.0.1) is in the string
"127.0.0.1\n192.168.1.1\n192.168.1.2" which it isn't because it's not a
list.
I have this right now.
domainlist local_domains = localhost : \
/etc/exim4/localdomains : \
${lookup mysql{select domain \
from eximconf.localdomains \
where enabled='yes' \
} \
{${sg{$value}{\N\ *\n\N}{ : }}} \
}
If I change to:
domainlist local_domains = localhost : \
/etc/exim4/localdomains : \
${lookup mysql{select domain \
from eximconf.localdomains \
where enabled='yes' \
} \
{$value} \
}
it would expand to:
domainlist local_domains = localhost : \
/etc/exim4/localdomains : \
electro-mechanical.com\nfederalpacific.com\nfptonline.com\nlinepower.com\nmetalcastingsco.com\nthereserveatleonardfarms.com
Does this make anymore sense?
