Hello All,
I'm having a problem where I am rejecting messages from one of our servers, but I'm not clear as to why. We are using: check_helo_access hash:/etc/postfix/helo_access We have in helo_access the following: ourdomain.com REJECT Helo Check helo_access ourdomain.net REJECT Helo Check helo_access x.x.x.x REJECT Helo Check helo_access localhost REJECT Helo Check helo_access I thought this would reject messages from someone saying they are our IP, saying they are localhost, or saying they are ourdomain.com and ourdomain.net, however it looks like we are rejecting the messages coming from server.ourdomain.net Exact error: 554 5.7.1 < server7.ourdomain.net >: Helo command rejected: Helo Check helo_access; Do I need to specify the subdomain otherwise it will consider this to be *.ourdomain.net? Is this rule not beneficiary ? I know SPF can handle this as well and we do use it. Thanks!
