http://bugs.exim.org/show_bug.cgi?id=1201 Summary: forwarding to a content-scanning site is a bounce- generator Product: Exim Version: 4.77 Platform: All OS/Version: All Status: NEW Severity: wishlist Priority: low Component: Delivery in general AssignedTo: [email protected] ReportedBy: [email protected] CC: [email protected] Created an attachment (id=535) --> (http://bugs.exim.org/attachment.cgi?id=535) Basic cutthrough routing The modern world of spammers faking envelope-from combined with antispam defences doing content-scanning, combined with 2MX service provided by separately maintained systems, results in a bounce problem. The attached patches implement an SMTP cutthrough-routing to attack the issue. The implementation is limited to best-effort, falling back to store-and-forward on error and on >1 (possibly routing-introduced) recipient. Is is triggered by a new "control=" recipient-ACL modifier. The basic facility is added by the "cutthrough" patch, which goes on top of the refactoring patch offered for bug 1184. The "dual-tls" patch extends the facility to make TLS connections where appropriate for the delivery. -- Configure bugmail: http://bugs.exim.org/userprefs.cgi?tab=email -- ## List details at https://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
