After updating our anti-spam rules/rDNS checks: probably more than expected Would it be an option to get something like the thing below for all error messages? 421 4.4.2 host.example.com Error: timeout exceeded - for more information see http://postmaster.domain.tld/[ip]-[code].html Where [ip] has to be replaced with the client IP and [code] has to be replaced with the error code (421 in this example). Using a certain error code for certain types of blocks would make it possible to display the correct page directly (or at least limit the input required from the person following the link). > > Almost none, because users cannot read [bounce messages]. > > They understand that the message did not arrive: > > http://funstoo.blogspot.com/2010/12/what-we-say-to-dogs-what-they- > hear.html > > This said, in a B2B context, a less experienced postmaster of a > remote domain may in some cases benefit from a link to a more detailed > explanation of an SMTP reject message. A fixed suffix for SMTP error > responses is probably the right cost/benefit trade-off. Informing other postmasters of a remote domain/server is the main reason we are looking for this option (or have to manually change things). If they could find why it was blocked and the reason it was blocked would probably reduce the support calls about the mailservers. Regards, Mark
