The setup is straightforward, but there are a few pitfalls.
This Full Qualified Domain Name is the full name of the server as <$hostname.$domainname>. When you login to the SMTP server, the server will identify itself with this name
220 <$hostname.$domainname> ESMTP Postfix
This name could be the name as defined in the MX DNS record for your domain. But this is not a requirement.
If your domain is high on the SPAM blacklist, add the name you would get with a reverse DNS lookup. These are not necessarily the same.
- Additional domain.
Add all domains that your server is defined as mail server according to the MX DNS records. This is at least 1 domain.
- SMTP relay
Fill in the SMTP server of your ISP. Note that SSL connection is not supported, only TLS or not-encrypted. Port could be 25, or 587, depending on your ISP. (do NOT use port 465 since that is explicitly used for SSL)
The configuration files for the HTTP deamon can be found in:
Several configuration files are recreated when you restart the HTTP service, so pay attention to which files are going to be edited.
The ‘source’ for the httpd.conf is httpd.conf-user in /usr/syno/apache/conf. But it might be cleaner to edir one of the included config files inside the /etc/httpd/conf/extra directory
The HTTP deamon can be restarted with:
/usr/syno/sbin/synoservicecfg --restart httpd-user
/usr/syno/sbin/synoservicecfg --restart httpd-sys
There are more services that can be restarted with the same tool. For a complete list, look at
There is a Synology package available that helps for easy installation, but it is based on an old version of Z-push. Better start a clean installation with the latest version. The installation notes can be found here:
Download the latest version from http://z-push.org/download/ and install it in /usr/share/z-push.
Log files can go to /var/log/z-push and settings can go to /var/lib/z-push.
Make sure all directories have owner http:http and correct writing permissions. Also add these directories to the open_basedir variable of PHP, which you can find in:
Control panel -> web services -> PHP settings
Modifications to config.php are minimal. Add the time-zone and if any of the default directories was changed, modify it here.
z-push-admin.php and z-push-top.php are executables and help you with the administration of Z-push. Run them without options to see if your installation is correct.
We need to define a redirection alias for the Z-push directory. This can be done in /etc/httpd/conf/extra/rhttpd-ssl.conf-user. Add the following line inside the :443 directive.
Alias /Microsoft-Server-ActiveSync /usr/share/z-push/index.php
This way, the directive is only valid on the SSL secured http connection, and not in the normal one.
Restart the server to see the effects.
The backup can be done while the sever is running. For restoring, the server must be stopped first.
Backup with mysqldunp:
mysqldump -u root -p <password> -h localhost --skip-lock-tables --single-transaction --databases zarafa > zarafa.dump.sql
Restore with mysql
mysql -u root -p <password> zarafa < zarafa.dump.sql
Sometimes the dump was created with chunks bigger then the server accepts:
ERROR 1153 (08S01) at line 6734: Got a packet bigger than ‘max_allowed_packet’ bytes
Then open a terminal with mysql -u root
and enter the following
mysql -u root
set global net_buffer_length=1000000;
set global max_allowed_packet=1000000000;
Leave the terminal open, and use the following in a new terminal:
mysql -u root -p <password> --max_allowed_packet=100M zarafa < zarafa.dump.sql
Don’t forget the attachments, since they are saved separately. Backup with:
tar -zcvf zarafa_attachment.tar.gz /var/lib/zarafa/
And restore the attachments with:
tar -zxvf zarafa_attachement.tar.gz
rm -rf /var/lib/zarafa/*
mv var/lib/zarafa/* /var/lib/zarafa
chown -R zarafa:zarafa /var/lib/zarafa
