http://bugs.exim.org/show_bug.cgi?id=1395 Summary: ignore_cache option for ACL dnslists Product: Exim Version: 4.80.1 Platform: Other OS/Version: Linux Status: NEW Severity: wishlist Priority: medium Component: ACLs AssignedTo: [email protected] ReportedBy: [email protected] CC: [email protected] Created an attachment (id=658) --> (http://bugs.exim.org/attachment.cgi?id=658) add +ignore_cache option to dnslists ACL check Today I had the specific need to be able to ignore the cached entries of a dnslists lookup, since the cache ignores the DNS TTL. I use my own RBLs to quickly block suspicious envelope froms and/or AUTH UIDs. If one keeps a connection after AUTH and sends several (up to our limits) mails the dnslist cache makes it impossible to get fresh lookups. Since there already was the possibility to set some options for dnslists (+defer...,...) I added +ignore_cache. Maybe this is practical for others, too. The option has to be used with care, because there is a chance to trigger a lot of DNS requests.
