whitelist dns check reverse postfix zimbra

[fferraro87]

Hi,

i've some problem sending messages to a domain, because i've this error :

Code: Select all

450 4.7.1 Client host rejected: cannot find your reverse hostname

PTR it's fine and well propagated, so how can i whitelist this check on postfix?

i've this zimbraMTARestriction :

Code: Select all

zimbraMtaRestriction: reject_non_fqdn_sender
zimbraMtaRestriction: check_client_access lmdb:/opt/zimbra/conf/postfix_rbl_override
zimbraMtaRestriction: reject_invalid_helo_hostname

and on /opt/zimbra/conf/postfix_rbl_override i've this lines :

Code: Select all

mx.levita.cloud OK
185.96.217.73 OK

but also if i put this MTA restriction (https://wiki.zimbra.com/wiki/New_Featur ... _addresses) i've always same error.

There is a way to bypass this postfix check?

Thanks

P.S. i've installed 8.7.11_GA_1854.NETWORK on Centos 7

If that really is your IP address then it would appear to have no reverse DNS as the initial error message stated:

Code: Select all

host 185.96.217.73
Host 73.217.96.185.in-addr.arpa. not found: 3(NXDOMAIN

)

yeah i know that for this IP there isn't still a right PTR, but i've already try with another correct reverse DNS.
But my question is if there is a way to whitelist this postfix check for some domains.


Thanks
