Siderit 0 Posted May 9, 2022 Share Posted May 9, 2022 Hello! I'm trying to set up Greylist in ESET Mail Security for Microsoft Exchange server. The issue i've encountered is mails from "mail*.google.com" HELO domain can't pass the Greylist. I guess this is due to the fact that google is using a random mail server with a different IP every time it resends the message. Is there a solution for the mentioned issue.

ESET Staff M.K. 17 Posted May 9, 2022 ESET Staff Share Posted May 9, 2022 Hi, you can add (google.com) domain to the Greylisting -> Domain to IP whitelist. Or to Antispam -> Ignored Domain to IP list, and ensure that checkbox "Use antispam lists to automatically bypass Greylisting and SPF" is on. Alternatively, you can check "Automatically bypass Greylisting if SPF check passes" under the SPF/DKIM section. Link to comment Share on other sites More sharing options...
Siderit 0 Posted May 11, 2022 Author Share Posted May 11, 2022 Hello M.K. "Automatically bypass Greylisting if SPF check passes" was turned on. I will test "Domain to IP whitelist" solution and report back. Altough I'm not sure if that list is populating correctly for me. I have 100+ Domain entries and only a handful get the + sign and the IP address list. Is that normal behaviour? Link to comment Share on other sites More sharing options...
