About SME Server

SME Server is the leading Linux distribution for small and medium

SME Server is freely available under the GNU General Public License and
is only possible through the efforts of the SME Server community.
However, the availability and quality of SME Server is dependent on
meeting our expenses, such as hosting costs, server hardware, etc.

The development team would like to thank all of those involved in this
release. More people are required to help with bug triage and
verification testing.

This release contains many new features, all released updates for SME
Server 7.4 and fixes for many reported problems. Upgrades will be
available by CD, the Software Installer and command line.

- Always perform a backup prior to major system upgrades
- An upgrade will preserve the existing data

Summary of changes from SME 7.5 RC1

Mail Server
- Update to ClamAV 0.96
- Increase MemLimit to 600M for clamav-0.96
- Remove spamassassin jobs from cron.daily that are no longer needed.
- Use HeloHost (if present) for SMTP auth proxy

Server manager
- Improve the HTML formatting of the modify quota panel to work in IE8.

- Require /sbin/mdassemble so mkinitrd works correctly.

Changes from SME 7.4

- The backup service has been made more robust:
  Allow many backups in the same day.
  Prevent launching a restore if all needed backups are not available.
  Do not allow a restore from a partial backup.
- Some valid passwords would fail due to how the backup directory was
  mounted, the use of a credentials file for mount.cifs now avoids this
- The e-mail now correctly identifies incremental and full backups.
- Make workstation-backup 'full backup allowed on'-setting stick across
  revisits of the Configure-page when set to: 'Sunday'

File Server
- A patch was added to support multiple samba roles, the change is
  transparent. However installing smeserver-adv-samba allows the user to
  take advantage of additional server roles as detailed in

- As part of a major update with translations we have added seven new
  Thai, Polish, Romanian, Estonian, Chinese, Norwegian (Bokmal),
- Other fixes include updated translations for the existing languages.

Mail Server
- Transport Layer Security (TLS) authentication capability has been
  added for incoming smtp ehlo requests.
- Implement correctly the subject line SPAM tagging functionality.
- The syntax of the smtproutes and SMTPSmartHost templates have been
  updated to avoid MX lookups
- Incoming mail could be incorrectly rejected by qpsmtpd plugin
- Update to qpsmtpd 0.83
- Update to ClamAV 0.96
- Increase MemLimit to 600M for clamav-0.96
- Remove spamassassin jobs from cron.daily that are no longer needed.
- HeuristicScanPrecedence is a new option in clamav 0.94.
  See http://wiki.contribs.org/Email#Heuristic_Scan
- Rotate Virus scanning log files
- Remove the external preloaded library, qmail-workaround, which was
  needed for qmail loopback connections if a domain MX resolves to This has now been replaced by a patch to qmail itself.
- Use HeloHost (if present) for SMTP auth proxy

Server manager
- The reconfigure warning is displayed in subsequent browser sessions of
  the server-manager when the server is updated from the Command Line,
  or after a reboot, if a full reconfiguration has not been performed.
- Allow to select "check for updates" daily, weekly or monthly in the
  Software Installer. Check for updates can also be disabled.
- Fix yum warnings about "another instance is running" when running a
  second instance of yum from another terminal.
- Improve the HTML formatting of the modify quota panel to work in IE8.

Webmail and Groupware
- Horde, imp, turba and ingo have been updated to the latest versions
- Patch to make sure username is always saved in lowercase to horde db's
- Allow FQDN and non-FQDN access to webmail.
- The spell checker in Horde Mail has been enabled for HTML composition.
- Obsolete smeserver-trean < 0.1-8 as it makes the sidebar menu of the
  webmail interface disappear.

Web Server
- Implement a database key (SSLv2) which allows to disable certificates
  signed with SSLv2, enabled by default to keep current behaviour.
- Add support for more MIME Types to Apache:
     Openoffice 1.x, Openoffice 2.x
     Microsoft Office 2007
- SSL Certificates will now use a SHA1
- SSL Certificates will now use a 2048 bits key size

Other fixes and updates
- From June 2009 smeserver-rkhunter was removed from smeos and made a
- Do not allow re-allocation of deleted Windows user profiles.
- Template sshd login grace time
- Correct the configuration of smartd to monitor hard disk status, but
  default to disabled.
- Display the boot time menu by default by removing the hiddenmenu entry
  from the default grub.conf to be in line with the documentation.
- Enable error logging for MySQL.
- When user or group names with a "." in the names exist,
  running /sbin/e-smith/audittools/aliases will show more than the
  expected list.
- Improve the quality of the mirrors by using a network mirror-list. The
  list is automatically generated hourly based on the status of the
  current mirrors. By using these mirror-lists it is ensured that people
  are directed to an updated mirror. When a mirror is added or removed
  the change will be available quickly and automatically. It also
  centralizes control of the mirror lists.
- Add yum-protect-packages support to prevent removal of needed
  packages. This stops accidental removal of core SME Server packages.
- Introduced (weak) kernel modules which are independent of kernel
  version. This means there is no need to update/rebuild kmods for each
  kernel update.
- Fix for VPN access failed with buffer too small errors.
- Require /sbin/mdassemble so mkinitrd works correctly.
