Mail client Configuration

This section will include how to get the best out of the Mail client program and web browser Zimbra interface.

Using the Zimbra Mail interface

The technology used to make the Zimbra web interface what it is can be accelerated through tuning your sysem.

Indeed sometime the web client will not even run, if for instance java is not installed.

Essentially use firefox which is quicker than Internet explorer Then install the Sun Java rather than the Microsoft Java

Using Zimbra with Outlook

With SSL:

• In /opt/zimbra/postfix/master.cf uncomment the following line:

#smtps    inet  n       -       n       -       -       smtpd

• Restart/Reload postfix

zmmtactl reload

You now have port 465 open for SSL SMTP. Make sure any firewall in place doesn't prevent access to the port.

In Outlook:

• add a new email account, type of either IMAP or POP, whatever you prefer.
• In the advanced settings configuration screen, enable SMTP over SSL (This server requires encrypted connection (SSL)).
• Also make sure to enable IMAP or POP over SSL.
• Change the SMTP port to 465

That should be all thats needed. Outlook doesn't deal well with SSL on port 25 using the STARTTLS command. It prefers immediate SSL negotiation followed by SMTP (old style SMTP over SSL)
