Who's blocking you for that spurious reason? Whoever's doing that is likely to do the same to anyone's magic smarthost. > Either that, or they have some alternate definition of RDNS that > doesn't allow us to send from a different server than we receive > email into. Gah, whoever "they" are shouldn't be on the Net with that kind of reasoning. Nobody can get mail to them reliably, and no one should jump through hoops to do so. Do you have the logs for these rejects? > How am I supposed to investigate issues when 25% of the people who > are blocking us now refuse to even send an NDR. By which you mean that they do not have systems smart enough to do envelope rejection for what you _think_ are non-weighted, single-source envelope infractions. It is, of course, possible that they are doing content-based deletion. If you don't get rejected, of course, you won't know. > I was looking for more of a technical solution and less of a moral > reproach. Understood, but you're bound to get such "life lessons" if you don't make it clear that you are not originating spam from your server, or you don't know if that is happening because you're not scanning. That's the nature of frazzled list users who fight spam all day, y'know? > In an age when the email server you are sending from can be > blacklisted for the actions of a single user, yes it does make sense > to compartimentalize outgoing email. Either scan it, compartmentalize it, or preferably both. As I said (and this _was_ a technical solution), get your app to send through a client-specific SMTP server on demand, rather than trying to kludge the server to do source routing. The client-specific servers could be totally remote smarthosts or other boxes on site (though separate Class Cs is really the only way to make that stick). --Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] SpamAssassin plugs into Declude! http://www.mailmage.com/products/software/freeutils/SPAMC32/download/release/ Defuse Dictionary Attacks: Turn Exchange Addresses into IMail Aliases! http://www.mailmage.com/products/software/freeutils/exchange2aliases/download/release/ To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
