Package: sendmail
Version: 8.13.4-3
Severity: grave
Justification: causes non-serious data loss
Hi Cowboy
I did desperately try to track down this error I saw on different systems:
Jun 28 13:53:41 go sendmail[18911]: j5SBrfKk018911: [EMAIL PROTECTED],
ctladdr=benoit (1024/100),
delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=31826, relay=[127.0.0.1]
[127.0.0.1],
dsn=4.0.0, stat=Deferred:Connection refused by [127.0.0.1]
Usualy after purging the config and re-installing sendmail everything was
fine.... until I
enabled IPv6 according to the advice in sendmail.mc file which reads:
------------
dnl # If you want to support IPv6, switch the commented/uncommentd lines
FEATURE(`no_default_msa')dnl
DAEMON_OPTIONS(`Family=inet6, Name=MTA-v6, Port=smtp, Addr=::1')dnl
dnl DAEMON_OPTIONS(`Family=inet, Name=MTA-v4, Port=smtp, Addr=127.0.0.1')dnl
DAEMON_OPTIONS(`Family=inet6, Name=MSP-v6, Port=submission, Addr=::1')dnl
dnl DAEMON_OPTIONS(`Family=inet, Name=MSP-v4, Port=submission,
Addr=127.0.0.1')dnl
------------
If you do this, sendmail only binds to the IPv6 Localhost and is not able to
transmit emails
from the MTA to the queue runner (or vice versa?).
You have to twitch submit.mc too:
------------
FEATURE(`msp', `[IPv6:::1]', `MSA')dnl
------------
I remember that older versions of sendmail didn't habe that problem, because
listening on IPv6
did mean you also opened the IPv4 socket.
Probably this has changes somewhen either in the Kernel or in sendmail itself.
