Hello, Sometimes I'm getting spam because I have a weakness in my configuration At the moment I have action TO-CLAM_SMTPD_IN relay host smtp://127.0.0.1:10027 match from src <clients> for domain <domaines> action TO-CLAM_SMTPD_IN match from any for domain <domaines> action TO-CLAM_SMTPD_IN The table clients is a file that contains IPs including 127.0.0.1, the table domaines is a list of domains that I host on my mail server
My problem is that a spammer is able to send mails to me when it uses a domain that I host.For example, the file domaines contains mydomain1.org and mydomain2.orgThe spammer doesehlo emtpmail from: <existing-mailbox-such-as-i...@mydomain2.org>rcpt to: <m...@mydomain1.org>data subject: This is a spam Spamspamspam . So I would tend to write a rule such asmatch ! from domain <domaines> for domain <domaines> action TO-CLAM_SMTPD_INConsidering that users that write from mydomain2.org to mydomain1.org match the first rule since they are local or authenticated or coming from one of the known IPs.But this rule is not correct Thank you
