hello guys ,

 

i'm facing a prblem on exchange 2019 CU3 .

 

i set the ipblocklistprovider as zen.spamhaus.org to prevent spam e-mails , but some e-mails from our costomer were blocked  .  i have checked the agent log ,and i can see the log which e-mails were blocked by zen.spamhaus.org .

 

1. i use test-ipblocklistprovider command to test the ipaddress of our customer , but the DNS lookup result from zen.spamhaus.org is "false"

 

2.  i try to add this ip address of our customer into ipallowlistentry , but no use , the e-mail still blocked .

 

does anyone can help on this ?

 

thank you very much .

hello@Marco Antonio da Silva

 

thank you for your reply .

 

i think the anti-spam function is working now because i can see lots of spam e-mails were blocked .

 

the problem is some e-mails from our customer's were blocked but i want to add them into the whitelist . 

 

the way i tried to is to add the ip address into IpAllowListEntry , but no use , the e-mails still blocked .

 

so i'm looking for someone can help on this .

 

thank you very much .
