Bug ID: 3146 Summary: smtp transport: option to filter host list Product: Exim Version: 4.98 Hardware: All OS: All Status: NEW Severity: wishlist Priority: medium Component: Transports Assignee: unalloca...@exim.org Reporter: jgh146...@wizmail.org CC: exim-dev@lists.exim.org Use case: doing ipv4-only to outlook-hosted domains. The dnslookup router can't filter because the MX result is not known early enough. Propose a bool, expanded, option on the smtp transport that can say yes/no for individual IP addrs resulting from the domain/MX/A lookup sequence. Considerations: when is the A or AAAA lookup done? If by the router then the tpt gets handed IPs and must (for this usecase) interpret v4 vs. v6. If by the tpt then the tpt gets handed names and could just specify v4-only A-lookup (supporting only the limited usecase. The "filter" mech above is more flexible - could eg. filter by AS or by country. -- You are receiving this mail because: You are on the CC list for the bug. -- ## subscription configuration (requires account): ## https://lists.exim.org/mailman3/postorius/lists/exim-dev.lists.exim.org/ ## unsubscribe (doesn't require an account): ## exim-dev-unsubscr...@lists.exim.org ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
