spam fighthing
greylisting
- delay for first mail from a domain
envelope-from checking
requirement to have a valid FQDN in HELO/EHLO (though it does not have to resolve).
postfix: directly sorting out in /etc/postfix/header_checks or /etc/postfix/body_checks
mxallowd, refuses mail on first mx and sees if delivery to second mx is tried
realtime blacklists like
socks.dnsbl.sorbs.net / dul.dnsbl.sorbs.net / ix.dnsbl.manitu.net / cbl.abuseat.org
sbl-xbl.spamhaus.org / bl.spamcop.net / web.dnsbl.sorbs.net
con: gotta trust the lists, they can censor that way
That still leaves me with a hundred to two hundred spams per day, all
but a few per week of which are caught by spamprobe, which is a Baysean
filter.
Reject senders with reverse DNS containing their IP
also catches homesend mails so.. really strips down.
Reject senders with reverse subdomain containing blacklisted works
(ex: *dyn*.foo.com, *dsl*.foo.com, *ppp*.foo.com, ...)
Reject senders which are not MX

HA-clustertesting
- Problem: many clusters (veritas vcs with io-fencing, steeleye lifekeeper) use scsi-3 persistant reservation to avoid splitbrain situations - this isnt emulated by kvm/xen/vmwave(any-version).
- unchecked solution: recent versions of solaris/opensolaris seem to offer this in their iscsi-target http://bugs.opensolaris.org/view_bug.do?bug_id=6415440

tvbrowser and other java-apps on linux not working any more
- Problem: “util.exc.TvBrowserException: Could not download group file http://tvbrowser.org/listings.” appears, “java.net.SocketException: Network is unreachable” or “It was not possible to create an Internet connection”
- Description: your linux-distro changed behaviour with an update, java is just trying ipv6 connection here and fails.
- Solutions:
- 'sysctl -w net.ipv6.bindv6only=0' orders to also try ipv4 connections, use /etc/sysctl.conf for the setting to survive reboots.
- or run java with these additional parameters: ”-Djava.net.preferIPv4Stack=true”
