Re: [Question] Building whitelists so that spamd greylisting can work without users perceiving delivery delays...

I've successfully run spamd on firewalls (as a frontend to either barracuda or SpamAssassin) and have really liked the reduction in SPAM volume. Unfortunately my employer's wife does not like the delays that this introduces into our mail delivery, since she uses email for quick turn-around communication. The main problem occurs with senders like Gmail, yahoo, hotmail, etc. ...i.e. all the senders that have large farms of smtp servers from which they can retry delivery after initial greylisting delay. I know this means I'm not doing proper whitelisting of those major sender domains, but I'm at a loss on how to best construct and maintain such a whitelist. Are there any up-to-date lists that already track the MTAs of these large mail providers? For e.g. google, I did dig -t txt _netblocks.google.com | grep spf and put the following in /etc/mail/nospamd 173.194.0.0/16 209.85.128.0/17 74.125.0.0/16 12.31.165.64/27 208.48.95.16/28 216.34.181.0/24 I left out 64.18.0.0/20 and 207.126.144.0/20 as they were sending me a lot of spam.

Re: current/macppc on Mac Mini
The saga continues: I tried to reinstall with 5.4-beta, and have a similar, but different problem now. To recall the previous situation: the kernel was confused about what 'cd0' and 'hd0' is, and I had to hardcode the bootpath into the kernel config. A patch from mpieuc...@nolizard.org solved it for me, but it is still considered not quite the right thing: On Dec 26 20:54:34, m...@online.fr wrote: I think I understand what goes wrong. The code responsible for matching the boot device to the actual kernel device on macppc is quite crude, especially for non-SCSI disks. Your bootpath specifies `disk@1' because the disk drive is the second device (slave) on the ATA channel, the cdrom drive being master. However, the kernel wants to match this information against a `wd1' device (as if there were two hard disks on the ATA channel). The kernel code needs to be fixed to use device_register() to match the boot path against actual attachment information, instead of walking the device tree at the end of autoconf. If nobody beats me to do this, I'll try to cook a diff in a few days.

Re: current/macppc on Mac Mini
I made the DOS partition start at 512 (and then 1024 and then everything under 4096 wherethe obsd part starts), but never could I mount that DOS partition ... Silly me, it's 1, not 512; and it mounts, and the ofwboot is NOT there, and not in the wd0i as designated by me either. So there is no copy of ofwboot on my disk. That is surely wrong. I will reinstall again, leaving the [a]uto disklabel untouched. Yes, this creates an 'i' entry for the DOS partition, which gets the ofwboot alright, and I can boot it, - just have to call it cd:,ofwboot in my OpenFirmware (or setup a devalias). When I do edit the disklabel during the install, but leave the 'i' untouched, or set one up that spans the (fdisk) DOS partition, the ofwboot gets installed to the right place too. So my conclusion is that you _need_ to have this partition in your disklabel; right? And the hd/cd confusion of my OpenFirmware has nothing to do with this, right? That would make the following paragraph from INSTALL.macppc not entirely accurate: For dedicated disks, macppc port boots off a boot program in an MSDOS filesystem. This is set up by the install program and no special setup is required. If I am right, should the 'i' partition that seems to be needed for a proper copy of the ofwboot be mentioned in INSTALL.macppc or perhaps http://www.openbsd.org/faq/faq4.html#InstProb ? Would other architectures that require some special partition to boot be affected similarly? Jan
dhcp address in /etc/hosts
I believe I have bitched about this before, but I have come to it again with new install. If I use [dhcp] to configure an interface during an install, the ephemeral DHCP-assigned address gets written into /etc/hosts. That address is meaningless after the reboot, possibly even conflicting when I later decide on a fixed IP for the machine. Should it be removed from /etc/hosts after the install, when we have DNS set up and all? Should it at least be mentioned in afterboot(8)? Jan

It does make the assumption that the DOS partition is the first spoofed
partition, i.e. 'i'. This should probably be revisited since we relaxed
the rules on partition naming a while ago.

It's done at the very end in the finish_up() function in install.sub.
Even my real wd0i partition, which is /usr/xobj

Your wd0i isn't an MBR partition.
That leads me to speculate that this ofwboot copy
is performed _before_ the installing user edits
the disklabel; but perhaps at that moment,
wd0i _is_ really the DOS partiton, and later

Nope. See above. :-)
Or did I miss it somewhere in the macppc install documentation
to leave 'i' alone so that ofwboot gets copied to the right place?
In INSTALL.macppc:
If you have DOS or Linux partitions defined on the disk, these will
usually show up as 'i', 'j', and so on.
and
If the disk is partitioned using MBR, the bootloader will be
automatically installed if you setup a small (a few MB) MSDOS
partition as position `i' in the label.
