http://bugs.exim.org/show_bug.cgi?id=1292 Summary: Add option to back DKIM -K temp files to POSIX shared memory Product: Exim Version: 4.80 Platform: All OS/Version: Linux Status: NEW Severity: wishlist Priority: medium Component: DKIM AssignedTo: [email protected] ReportedBy: [email protected] CC: [email protected] Created an attachment (id=587) --> (http://bugs.exim.org/attachment.cgi?id=587) dkim_shm implementation Attached is a patch that adds an SMTP transport option of dkim_shm. When the expansion of dkim_shm evaluates to either "1" or "true", Exim will use POSIX shared memory to store the temporary, on-the-wire formatted message to be DKIM signed. Otherwise, the original code path of creating a temporary file in the spool directory will be used. When enabled, this change means that -K files will not hit disk (OS caveats about how POSIX shared memory is implemented still apply). For modern Linux installations, the -K files will end up on a tmpfs partition mounted at /dev/shm. -- 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/ ##
