I am running SIMS 1.7 on a G3/266. The system has been working flawlessly for the past couple of years. Only have to restart about once every 2 months. Currently have over 250 user accounts. I have been using all anti-spam options such as Client Hosts, Relay for Clients Only, Verify Return Paths, Black Listed, and Use Blacklist DNS Server:
I received the following e-mail message on the Postmaster account. ----------------------------------------------------------------------------- This is a warning message. You are receiving this message because this, or one of your mail relays (see below for details) is open to third party (free) relaying and has been abused to send unsolicited bulk email (spam) to America Online, Inc.'s email system. Below, you will see output from our database indicating which tests we performed on your system, and the time at which the last test was performed. For example, if you see: mail from:<[EMAIL PROTECTED]> rcpt to:<[EMAIL PROTECTED]> it means we were able to send a piece of email with a "from" address of "[EMAIL PROTECTED]" through your system, back to the email account "[EMAIL PROTECTED]". (The email address "[EMAIL PROTECTED]" doesn't exist -- it's greater than 16 characters -- but the fact that your system tried to deliver to that address indicates that your server is available for free relaying. We encourage you to use this email address as a test... you will receive undeliverable email back from AOL's Mailer-Daemon if you are open to free relaying.) Here's your server data: Date: Tue Aug 12 10:09:00 2002 mail from: <[EMAIL PROTECTED]> rcpt to: <CloseYourOpenRelay%aol.com@yourhostname> You will receive a series of warning messages. If this is your first warning message, you have 5 business days from the date AOL sent the message to address the above security issues before you server may be blocked from sending mail to the AOL member base. If your server is intentionally open and you wish it never to be tested again, please send an email to [EMAIL PROTECTED] with the subject line "forever open, don't test" and your IP address(es) in the body of the email. AOL will then put your IP(s) into the Forever Open Don't Test list. *** Please keep in mind that if you do this, your server will be blocked and will REMAIN blocked until you send an email to [EMAIL PROTECTED] and ask AOL to start testing your server again. *** ----------------------------------------------------------------------------- I tested and verified the following: 1. I can relay messages from TCP/IP addresses listed in the Client Hosts. 2. I cannot relay messages from TCP/IP addresses not listed in the Client Hosts. 3. I can connect to the POP host (check mail now) and immediately send the relay message from a TCP/IP address not listed in the Client Hosts. I followed the AOL instructions and tried sending a message (using send mail now and not check mail now) from a dial-up account using their e-mail server and a TCP/IP address not listed in the Client Hosts and it went through. Any info would be greatly appreciated.
