How secure is Group-Office?

We've done as much as possible to make Group-Office secure:

  • A penetration test has been done by two security companies.
  • We've encrypted the Group-Office passwords with the PHP crypt function using a unique salt for each user so making rainbow tables is impossible.
  • For brute force attacks we recommend using Fail2ban
  • Other sensitive information in the database is two way encrypted
  • Permissions for each user are checked at each server request inside Group-Office.

Additionally, you should always use SSL encryption so that all data is send encrypted to and from the client computer to the server and you should use strong passwords and change passwords frequently. We use SSL encryption and a firewall program that blocks attackers after five failed login attempts on all available services on the server.

Technical questions / Configuration

How can I raise the maximum filesize of uploads?

First you need to configure php.ini (or /etc/apache2/conf.d/groupoffice.conf or /etc/apache2/sites-enabled/* if you installed the packages) and edit "upload_max_filesize" to the desired amount. Then edit your "config.php" file and change "max_upload_size" for the files module and "max_attachment_size" for e-mail attachment. Please be aware that for sending large e-mails you will need 3 times the amount of memory. So for 20MB attachments you'll need to set PHP's memory_limit to at least 60MB.

How van I reset a lost password in MySQL?

Edit the user record in the "go_users" table. Change the field password_type to "md5" and change the field "password" to the new password and encode it with the MD5 function. After a login Group-Office will encrypt the password to a more secure format.

How can I change the font of my emails and email templates

You can't select a font in the editor. The font is globally defined in config.php. The administrator can change the default font:

$config['$html_editor_font']="font-size:13px; font-family:Arial, Helvetica, sans-serif;";
