I can send mail from any domain with a valid MX record. i.e.
[EMAIL PROTECTED] [EMAIL PROTECTED] To any valid email address. (Without authentication) So my mail server is acting like a open relay. My server.tab is configured as supplied. All I want is @fifelearninghomes.org.uk to be the only sender address to be allowed to 'relay' through the smtp server. ?? Graham -----Original Message----- From: Lynn A. Roth [mailto:[EMAIL PROTECTED]] Sent: 01 May 2002 14:37 To: [EMAIL PROTECTED] Subject: [xmail] Re: Help! Spammers You have: "CheckMailerDomain" "1" in your server.tab, which will check to see if the domain exists in the DNS. What mail goes through? Mail to users on the server? Or mail to users on another machine? (relaying) If it is mail going to local users, then your server is acting correctly.

If the users are coming from unknown addresses, they will have to use SMTP authenication or use Pop before SMTP by enabling EnableAuthSMTP-POP3 in your server.tab. (POP before SMTP defaults to on, you going by your example, you should be all set...) See the docs for more information.
