Some mail clients will use a system called "Autodiscover" to figure out which settings to use for the pop/imap/smtp settings. You can set this up if you'd like, it basically requires a subdomain and a SRV record. You can add the SRV record into any domain you want to use these settings for.

If you've got a global SSL certificate in Postfix/dovecot for your hostname, this would be a good way to ensure clients use the correct value, so they don't get SSL certificate errors.

Let's assume you're going to have your clients with datahead.biz connect to host.datahead.biz for both IMAP and SMTP. So we have a subdomain called host.datahead.biz to store the XML, where host.datahead.biz is a Server FQDN .

1.Setup a SRV record in the datahead.biz DNS zone:
_autodiscover._tcp.datahead.biz. 3600 IN SRV 10 10 443 host.datahead.biz.

2.Next, Creat a file named autodiscover.php on /usr/local/apache/htdocs/
# vi /usr/local/apache/htdocs/autodiscover.php
