Seiichiros mail-setup adapted for Ubuntu: Postfix + Dspam/ClamAV + Dovecot2
To use Seiichiros mail-setup with Ubuntu 10.04 I have to make a couple of changes. I will describe here only these changes. The complete setup can be found on Seiichiros Website.
The Ubuntu 10.04 standard repository doesn't offer a package for dovecot2. Dovecot1 doesn't support lmtp and the antispam plugin has a bug. With use of an additional repository the configurations can be made as described by Seiichiro. I had to made a few adjustments and I integrated support for ClamAV.

Arch: VLANs in rc.conf
- the package vconfig is needed in order to use VLANs
pacman -Sy vconfig
- There were several approaches in the Forum to configure VLANs in rc.conf. The Problem is: therefor its necessary to do extensive changes in “/etc/rc.d/network”.
- After a update its possible that all changes are gone.
- I wasn't interested in doing multiple changes in “/etc/rc.d/network” after updates.
- That's why I write my own variant. It's only needed to change two lines.
- With my Script it's only Possible to add VLAN and not to remove.
- “vconfig” is designed that after a reboot VLAN interface are not configured.
- If you want to achieve more, further changes have to include into “/etc/rc.d/network” and I wanted to avoid this.
Setup:
- First the Script, put it into “/etc/conf.d”.
- create_vlans
#!/bin/bash #FILES # /proc/net/vlan/config # /proc/net/vlan/[vlan-device] # rc.conf: # VLANs # #VLAN_DEVS=(eth0.6) ###### # /etc/rc.d/network # vlan settings #[ -f /etc/conf.d/create_vlans ] && . /etc/conf.d/create_vlans # ### Variables ### LSMOD_PATH="/usr/bin/lsmod" VLAN_PATH="/proc/net/vlan/" VCONFIG_PATH="/usr/sbin/vconfig" # ### Functions ### vlan_add() { if [ -e $VCONFIG_PATH ];then /usr/bin/lsmod | grep 8021q > /dev/null 2> /dev/null if [ $? == 0 ];then if [ ! -e $VLAN_PATH$1 ];then VLANS_DEV=$1 VLAN_IFACE=`echo $VLANS_DEV | cut -d "." -f1` VLAN_ID=`echo $VLANS_DEV | cut -d "." -f2` $VCONFIG_PATH add $VLAN_IFACE $VLAN_ID > /dev/null 2> /dev/null fi else echo "8021q Module not loaded" fi else echo "please install vconfig: pacman -S vconfig" fi } vlan_rem() { vconfig rem $1 } # ### Main ### if [ ! -e $LSMOD_PATH ];then echo "/usr/bin/lsmod not available, unable to check vlan module" else for vlans in ${VLAN_DEVS[@]}; do vlan_add $vlans done fi
- Adapt “/etc/rc.d/network” Attention: the changed are gone after update initscripts.
- Add these lines before the other includes.
# vlan settings [ -f /etc/conf.d/create_vlans ] && . /etc/conf.d/create_vlans
configure VLANs
- VLAN interfaces now can be entered in the rc.conf.
- With “VLAN_DEVS=()” the interfaces were created [Interface.VLAN_ID].
- Then you can assign an IP-Adresse to the interface. The interface name is “vlan6” for example. This name must not contain “.” or “ ”.
Example:
#VLANs VLAN_DEVS=(eth0.6) interface=eth0 address= netmask= broadcast= gateway= interface=eth0.6 address=172.16.10.1 netmask=255.255.0.0 broadcast=172.16.255.255 gateway=
