Hi Ian Ultimately we have a platform that accepts mail from users on our IP allocation and also for domains of our users. This mail is then scored depending on the likelihood of it being SPAM. A central filtering platform will then take out mail that breaches this threshold. This accounts for taking out about 80% SPAM. This mail is then black holed.
However any mail that does get through that is destined for a resolvable email address will then be delivered to the back end server(s) via and Exim box running manualroutes. Should this message be undeliverable (through the mailbox not existing) then this is sent back to the sender. I believe this is common practise and as describes, required as a NDR. As our off-network mail is delivered from a small cluster of servers we keep finding that these servers are listed on the likes of SpamCop which then disrupts delivery of legitimate mail to our users. We are looking at putting in a new anti-spam application shortly but in the meantime we need to try and filter out what are legitimate NDR's and which are bounced SPAM messages Ian Eiloart wrote: > > > > --On 31 October 2007 13:19:09 +0000 "Phil (Medway Hosting)" > <[EMAIL PROTECTED]> wrote: > > >> In the words of Shaggy - It Wasn't Me !!! >> >> Original question was from "ikearns". >> > > Sorry, Phil. > > Ikearns, what exactly are you trying to do? > > -- > Ian Eiloart > IT Services, University of Sussex > x3148 > > -- > ## List details at http://lists.exim.org/mailman/listinfo/exim-users > ## Exim details at http://www.exim.org/ > ## Please use the Wiki with this list - http://wiki.exim.org/ > > -- View this message in context: http://www.nabble.com/Exim-dropping-NDR---Non-Delivery-Receipts-tf4717314.html#a13545258 Sent from the Exim Users mailing list archive at Nabble.com. -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
