As I understand that relaying is a fundamental part of delivering an email, I'm guessing this configuration is not normal. Our SMTP server hits the ISP's SMTP server which then hits the customers SMTP/POP server. In most cases, your SMTP server will just find a direct route to the destination server and only the sending server and receiving server will be involved without a server being in the middle, no? Is it not classed as a form of open relaying, even though there is a form of authentication (IP check) on it? Both our external IP and the ISP's email IP are not listed on any blacklist (checked with dnsstuff.com). Again, thanks for the quick reply, it's appreciated. -- View this message in context: http://www.nabble.com/Scoring-Issue-tf2151288.html#a5941127 Sent from the SpamAssassin - Users forum at Nabble.com.

Your setup does not sound any different to many others. We are shooting in the dark here, you need to ask your customers to provide you with the reasons that they blocked your messages. As they are the ones that are blocking they are the only ones who can tell you what the reasons are. If they are using SpamAssassin and they can provide you with the list of rules that hit your emails, then this list might be able to give you advice on how to stop this happening in the future. Without that we are just guessing. -- Anthony Peacock CHIME, Royal Free University College Medical School WWW:http://www.chime.ucl.ac.uk/~rmhiajp/ If you have an apple and I have an apple and we exchange apples then you and I will still each have one apple.

In most cases, your SMTP server will just find a direct route to the destination server and only the sending server and receiving server will be involved without a server being in the middle, no? Eh - sort of. Your SMTP relayhosts/smarthosts to your ISP. The ISP server will usually do an MX query for the destination domain of the e-mail, and deliver to that server. That server is not necessarily the post-box server - it may have to feed the mail to another server, and so on. Is it not classed as a form of open relaying, even though there is a form of authentication (IP check) on it? Both our external IP and the ISP's email IP are not listed on any blacklist (checked with dnsstuff.com). No, smarthosting isn't open relaying. While dnsstuff.com may not list them, I'd still ask the customer to get the rules that scored the e-mail high enough for quarantine. Only by seeing the rule names will you be able to determine what characteristics of the e-mail are triggering the quarantine.
