Hello,
we are using qpsmptd 0.32. Now the mail from cbsig.net is blocked
by require_resolvable_fromhost plugin . As this domain's mail is coming from
more than a server I can't set the whitelist for a particualr IP address.
These are some of the logs of my qpsmtpd:
logterse plugin: ` 64.30.237.62 proxy1068-fe.tm.cbsig.net
proxy1068.tm.cbsig.net require_resolvable_fromhost

You can see that everytime it is sending mail from different servers, so I
am not able to whitelist a particular IP. I tried the dig command of each
proxy* servers the IP was resolving. Also I tried the dnsmx command and got
the result as follows :
# dnsmx proxy1055.tm.cbsig.net
0 proxy1055.tm.cbsig.net
When I tried to run the dnsmx command for the domain it returned
# dnsmx cbsig.net
10 mail.cbsig.net
Is this problem happens because of MX record ? Please tell me why this
happens and how we can solve this issue.
Thanks
