http://bugs.exim.org/show_bug.cgi?id=615 Summary: named localpartlist list caching problem with local_part_suffix and local_part_prefix Product: Exim Version: 4.68 Platform: All OS/Version: All Status: NEW Severity: bug Priority: high Component: List matching AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] CC: [email protected] There is a problem with the way Exim 4.68 handles caching of named localpartlist lists, when used with the router options of local_part_suffix and local_part_prefix. Specifically, Exim will cache negative lookups (as it should), but then improperly uses the previous cached negative lookup even when the key changes as a result of local_part_suffix or local_part_prefix. To easily reproduce the problem, use this complete config file in its entirety and save it as "/tmp/testconfig": #------------------------------------------------------------ qualify_domain = mydomain.com localpartlist aliases = joe:sam:tom begin routers router1: driver = accept local_parts = +aliases condition = false transport = local_delivery router2: driver = accept local_parts = +aliases local_part_suffix = -real transport = local_delivery begin transports local_delivery: driver = appendfile file = /tmp/${local_part} #------------------------------------------------------------ Then, run the following command to test the router: /usr/lib/sendmail -bv -d+route -C/tmp/testconfig Once prompted by Exim, enter a test address of: joe-real The result you will receive will be: routing [EMAIL PROTECTED] --------> router1 router <-------- local_part=joe-real domain=mydomain.com checking local_parts joe-real in "joe:sam:tom"? no (end of list) joe-real in "+aliases"? no (end of list) router1 router skipped: local_parts mismatch --------> router2 router <-------- local_part=joe-real domain=mydomain.com stripped suffix -real checking local_parts cached no match for +aliases cached lookup data = NULL **> joe in "+aliases"? no (end of list) router2 router skipped: local_parts mismatch no more routers [EMAIL PROTECTED] failed to verify: Unrouteable address Note the line above that I have highlighted. That is where the problem lies, because "joe" is *in* the +aliases named list. However, it's using the cached negative lookup associated with the address, but failed to recognize that the lookup key is different (i.e. "joe" instead of the cached negative value for "joe-real"). This can cause definite problems for anyone using the prefix or suffix options. -- Configure bugmail: http://bugs.exim.org/userprefs.cgi?tab=email -- ## List details at http://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
