Please correct me if I am wrong. What Erik means is that, by default, all SMTP communication will go through port 25. It includes server to server and client to server communication. If you setup rblsmtpd (or similar program) to check the incoming email again spam, all emails going through port 25 will be checked. It includes the emails submitted by you and your users.
In order to avoid such problem, you may divide the emails into two portion: 1. Email from other servers - It will use port 25 and rblsmtpd will scan the incoming mail as usual. 2. Email from local users - Local users will need to change their mail client setting, so that it will submit email to the server by using port 587 (the submission port). There's no rblsmtpd checking on port 587. But instead, users must authenticate himself / herself before they can submit email. Best regards, Bill On 11/27/06, Jon M.

Can you elaborate on what you mean by it putting up submission port 587 without blacklists? I don't mind not using the RBL on my server, I was just not understanding why I was running into the problem. I guess the RBL is seeing a connection being made from my laptop from a cable connection and blocking it before it sends out. -----Original Message----- From: Erik Espinoza [mailto:[EMAIL PROTECTED] Sent: Sunday, November 26, 2006 11:11 PM To: [email protected] Subject: Re: [qmailtoaster] NJABL DNSBL > Why is qmail checking the NJABL when I'm SENDING email?

Best bet is to upgrade to the qmail-toaster package on my site, http://devel.qmailtoaster.com/ as it will put up Submission port 587 without blacklists.
