Group-Office installation on Debian 6.x

I used the auto installation as guided by the group-office wiki. However, for conveniences, quoting the contents once again:

Easy installation on a dedicated Debian or Ubuntu server

This is the easiest way of installing Group-Office. With the debian packages everything is configured automatically and Group-Office updates will be installed automatically when you update your Debian or Ubuntu system.

Install Debian >= 5 or Ubuntu >=8.10

Note: All the commands here use "sudo". This is necessary on Ubuntu. If you are on Debian you can use the "su" command first and execute all the commands without "sudo".

Add the following line to /etc/apt/sources.list

deb threeseven main

You can do that easily by executing the following command in the terminal:

echo -e "\n## Group-Office repository\ndeb threeseven main" | sudo tee -a /etc/apt/sources.list

To authenticate the packages you need to import the public key by running the folowing commands: In ubuntu don't do this as root because you will have trouble with the gpg keyring permissions. On debian you can do this as root and omit the sudo command before the apt-key add command.

gpg –keyserver hkp:// –recv-keys 01F1AE44

gpg –export –armor 01F1AE44 | sudo apt-key add –

Note: The keyservers are often very slow. If the keyserver doesn't respond you may try this one instead: hkp:// Continue reading “Group-Office installation on Debian 6.x” »


Postfix Configuration on Centos 5.x

Let's install Postfix and Dovecot (Dovecot will be our POP3/IMAP server):

yum install cyrus-sasl cyrus-sasl-devel cyrus-sasl-gssapi cyrus-sasl-md5 cyrus-sasl-plain postfix dovecot

Next we configure SMTP-AUTH and TLS:

postconf -e 'smtpd_sasl_local_domain ='
postconf -e 'smtpd_sasl_auth_enable = yes'
postconf -e 'smtpd_sasl_security_options = noanonymous'
postconf -e 'broken_sasl_auth_clients = yes'
postconf -e 'smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination'
postconf -e 'inet_interfaces = all'
postconf -e 'mynetworks ='

We must edit /usr/lib/sasl2/smtpd.conf so that Postfix allows PLAIN and LOGIN logins. On a 64Bit Centos 5.0 you must edit the file /usr/lib64/sasl2/smtpd.conf instead. It should look like this: Continue reading “Postfix Configuration on Centos 5.x” »
