Did you try using .dhs.gov
In /usr/local/etc/postfix/postgrey_whitelist_clients.local? -----Original Message----- From: [email protected] <[email protected]> On Behalf Of James B. Byrne Sent: Friday, November 26, 2021 2:33 PM To: [email protected] Subject: Postgrey - whitelisting subdomains I looked for a postgrey list to ask this, but the one that I found does not seem to have any archives after 2019 so I came here instead. If there is somewhere else to ask this please let me know. We use postfix with postgrey. We have a whitelist /usr/local/etc/postfix/postgrey_whitelist_clients.local According to the man page: Whitelists Whitelists allow you to specify client addresses or recipient address, for which no greylisting should be done. Per default postgrey will read the following files: /usr/local/etc/postfix/postgrey_whitelist_clients /usr/local/etc/postfix/postgrey_whitelist_clients.local /usr/local/etc/postfix/postgrey_whitelist_recipients In /usr/local/etc/postfix/postgrey_whitelist_clients.local we have dhs.gov: [root@mx31 ~]# grep dhs.gov /usr/local/etc/postfix/postgrey_whitelist_clients.local dhs.gov The problem is that postgrey grey-listed this email: Nov 26 13:43:36 mx31 postgrey[27438]: action=greylist, reason=new, client_name=mx0f-00376703.gpphosted.com, client_address=67.231.155.98, [email protected], recipient=<[email protected]> After a delay the send/receive pair was auto whitelisted. However, I was given to understand that domain entries in the whitelist also applied to subdomains. Also from the postgrey man page: The following can be specified for client addresses: domain.addr "domain.addr" domain and subdomains. Why was email from dhs.gov grey-listed?
