Hi.
I was hoping to get some pointers on how to do the following sysadmin
chores:
* I'm running sendmail+cyrus, and I'd like to configure a milter with
some simple
rules (for instance, don't accept email from sites that don't have
IN-ADDR.ARPA
records)
* I'd also like to set up autofs, but it seems to be failing... I tried
to set up an example
/home mountpoint like the auto.master man page suggests, but they
don't give an
example of what /etc/auto.home would look like (and just coping
auto.net into it
doesn't work). Suggestions?
* I tried to edit /etc/sysconfig/network to have "NETWORK_IPV6=no" but
it still
wants to bring up IPV6 networking anyway:
eth0 Link encap:Ethernet HWaddr 00:11:09:04:D5:2A
inet addr:192.168.1.5 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::211:9ff:fe04:d52a/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX bytes:1446018 (1.3 MiB) TX bytes:475699 (464.5 KiB)
Interrupt:177 Base address:0xc000
is this a bug? What am I missing?
* Lastly, when I start up my mail UA, it complains about the certificate
coming from
the host being signed localhost.localdomain... Is there a
walk-through on how to set
up the various certificates required for using SSL/TLS for sending
email from a
client? How do I set up certificates for individual users, for instance?

similarly, I can't send email using SSL when connecting to my
sendmail server...
(but TLS seems to work).
* Ditto for Cyrus. I can't use secure authentication:
Sep 27 12:38:42 mail imaps[5986]: starttls: TLSv1 with cipher AES256-SHA
(256/256 bits reused) no authentication
I'm using Thunderbird, if that makes any difference.
Any guidance appreciated.
Thanks,
