--- Comment #4 from Jeremy Harris <[email protected]> --- (In reply to Jasen Betts from comment #3) > The seems to be on the caller to guess which of ip6 or ip4 the mx record > will resolve to this time. Docs say: "The first interface of the correct type (IPv4 or IPv6) is used for the outgoing connection" (the "interface" option takes a list) - so that does not seem to be so. SO_BINDTODEVICE in Linux socket(7) seems relevant, but implies that > exim binds the outgoing socket to the ip address I give for interface every > time might even be restrictive; that if you spec addr "A" for an interface that also has a "B" for a different subnet, you won't be able to connect to hosts on that "B" net. This feels like something that will differ across network-stack implementations, too. Anyone feel like testing it? -- 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): ## [email protected] ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
