When I disable the interface before starting mta, then the mta does not allow sends to the hosts that it couldn't connect to on start. Ie, if my host is mail.internet.com, and when starting mta the mta can't reach mail.internet.com, then all sent email will get stuck with a logged message of network is unreachable.
I was thinking of removing exim4 from rc2.d, and making a cron task that will check if I have ping to mail.internet.com, and once I have it, I would start exim4. Do I have any other choices? This is fairly annoying, perhaps I should report this as a bug to the exim maintainers??

It looks like exim4 is trying to resolve the ip of hostname (including domain), and it insists on connecting to the dns server, having an entry in hosts doesn't seem to help (same behavior with using host, ping does work through hosts) Any idea on how to make host and exim4 go through hosts to resolve hostname? That is I have hostname litshi, domain luna.local (in resolv.conf). both strace and tcpdump show a connection to the dns server to resolve litshi.luna.local. strace -f produces (192.168.0.1 would be the dns server) [pid 17824] close(4) = 0 [pid 17824] munmap(0x40355000, 45100) = 0 [pid 17824] socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 4 [pid 17824] connect(4, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("192.168.0.1")}, 28) = 0 [pid 17824] send(4, "n\273\1\0\0\1\0\0\0\0\0\0\6litshi\4luna\5local\0\0"..., 35, 0) = 35 [pid 17824] gettimeofday({1085060186, 109435}, NULL) = 0 [pid 17824] poll( <unfinished ...> [pid 17803] rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0 [pid 17803] rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0 [pid 17803] rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0 [pid 17803] rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0 [pid 17803] rt_sigaction(SIGINT, {0x8075fd0, [], SA_RESTORER, 0x4008f658}, {0x80837d0, [], SA_RESTORER, 0x4008f658}, 8) = 0 [pid 17803] waitpid(-1, Process 17803 suspended <unfinished ...> [pid 17824] <... poll resumed> [{fd=4, events=POLLIN}], 1, 5000) = 0 [pid 17824] send(4, "n\273\1\0\0\1\0\0\0\0\0\0\6litshi\4luna\5local\0\0"..., 35, 0) = 35 [pid 17824] gettimeofday({1085060191, 111916}, NULL) = 0 [pid 17824] poll( <unfinished ...> > -- > Tzafrir Cohen +---------------------------+ > http://www.technion.ac.il/~tzafrir/ |vim is a mutt's best friend| > mailto:[EMAIL PROTECTED] +---------------------------+ > > ================================================================= > To unsubscribe, send mail to [EMAIL PROTECTED] with the > word "unsubscribe" in the message body, e.g., run the command echo > unsubscribe | mail [EMAIL PROTECTED] > > > +++++++++++++++++++++++++++++++++++++++++++ > This Mail Was Scanned By Mail-seCure System > at the Tel-Aviv University CC. > ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED] ================================================================To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
