Are your IP addresses on some spam blacklist?
yes i'm using static IP address...
i do not have PTR/SPF records (but i have other boxes at another isp without PTR records) they have no such problem...
btw, how do i set PTR / SPF? do i set from ISPConfig? set to what value?
i've checked against http://www.dnsstuff.com/
- no error except
PTR test: "IPADDR has no reverse DNS entry; some mail servers may not accept your mail"
pls help me understand...
my main ISPConfig hostname is quatiseasia.com
and MX is mail.quatiseasia.com
if i add a new domain using ISPConfig (eg newdomain.com) with same IP address as quatiseasia.com,
when i send OUT a mail from email@example.com
, the receipient mail server should be "talking" to mail.quatiseasia.com, or mail.newdomain.com ?
or does it matter?
