Edit /etc/ispcp/bind/parts/db_e.tpl
and change the following things:
1. Minimum TTL (standard 3H) to 1H
2. MX records
Remove the line:
IN MX 10 mail.{DMN_NAME}.
and add following:
IN MX 1 ASPMX.L.GOOGLE.COM. IN MX 5 ALT1.ASPMX.L.GOOGLE.COM. IN MX 5 ALT2.ASPMX.L.GOOGLE.COM. IN MX 10 ASPMX2.GOOGLEMAIL.COM. IN MX 10 ASPMX3.GOOGLEMAIL.COM.
3. CNAME
3.1 Remove all CNAME that points to mail, imap, pop, pop3, smtp, relay & webmail. (You can change webmail to: ghs.google.com instead of www.)
3.2 And add a CNAME for all different services you want to host. All services should point to ghs.google.com, and the verification code to google.com!
calendar IN CNAME ghs.google.com. start IN CNAME ghs.google.com. {verificationcode} IN CNAME ghs.google.com.
Don't forget the ending dot after ”.com”.
The verification code looks similar to “googlefffggghhh34435665” and you can find this in your controlpanel at Google Apps.
