These worked for me ... I host through THE PLANET formerly EV1 SERVER

Step 1.  Login in to your Server Command Control panel - which at my hosting provider is separate and distinct from PLESK - and go to the place where you manage the DNS settings for your domain.  Add the MX pointers as provided in the generic instructions for Google Apps ... be careful to set the MX pointers to  .yourdomain.com. versus to mail.yourdomain.com.  This got me confused and caused problems - the mail.yourdomain.com. pointer will not work correctly:

yourdomain.com.                 NS              ns1.ev1servers.net.            
yourdomain.com.                 NS                 ns2.ev1servers.net.         
yourdomain.com.                 MX                 1 ASPMX.L.GOOGLE.COM.
yourdomain.com.               MX                 5 ALT1.ASPMX.L.GOOGLE.COM.
yourdomain.com.               MX                 5 ALT2.ASPMX.L.GOOGLE.COM.
yourdomain.com.               MX                 10 ASPMX2.GOOGLEMAIL.COM.    
yourdomain.com.               MX                 10 ASPMX3.GOOGLEMAIL.COM.    
yourdomain.com.               MX                 10 ASPMX4.GOOGLEMAIL.COM.    
yourdomain.com.               MX                 10 ASPMX5.GOOGLEMAIL.COM.    
calendar.yourdomain.com.     CNAME             ghs.google.com.
docs.yourdomain.com.         CNAME             ghs.google.com.
googlexyzabcxy1ab2x3y4.yourdomain.com.     CNAME     google.com.        
mail.yourdomain.com.         CNAME             ghs.google.com.
start.yourdomain.com.         CNAME             ghs.google.com.
cpanel.yourdomain.com.         A             your ip address
ensim.yourdomain.com.         A             your ip address
ftp.yourdomain.com.             A             your ip address
lists.yourdomain.com.         A             your ip address
yourdomain.com.                 A             your ip address
plesk.yourdomain.com.         A             your ip address
www.yourdomain.com.         A             your ip address

Step 2.  DELETE any and all references that point to your server\\\\'s IP address that have to do with mail.

Step 3.  LOGIN to your  PLESK control panel and turn off mail for your domain.  Again critical.

Step 4.  This step may be optional but I did it just to be on the safe side.  While you are within PLESK, navigate to the DNS settings, and replicate the MX settings you set up through the support center.  Again, delete any DNS settings that would resolve mail to your IP address versus to google.

yourdomain.com.    NS    ns.yourdomain.com.

ns.yourdomain.com.    A    youripaddress
    yourdomain.com.    A    youripaddress
    calendar.yourdomain.com.    CNAME    ghs.google.com.
    docs.yourdomain.com.    CNAME    ghs.google.com.
    ftp.yourdomain.com.    CNAME    yourdomain.com.
    googlexyzabcxy1ab2x3y4.yourdomain.com.   CNAME    google.com.
    mail.yourdomain.com.    CNAME    ghs.google.com.
    start.yourdomain.com.    CNAME    ghs.google.com.
    www.yourdomain.com.    CNAME    yourdomain.com.
    yourdomain.com.    MX (5)    ALT1.ASPMX.L.GOOGLE.COM.
    yourdomain.com.    MX (10)    ASPMX3.GOOGLEMAIL.COM.
    yourdomain.com.    MX (0)    ASPMX.L.GOOGLE.COM.
    yourdomain.com.    MX (5)    ALT2.ASPMX.L.GOOGLE.COM.
    yourdomain.com.    MX (10)    ASPMX1.GOOGLEMAIL.COM.
    yourdomain.com.    MX (10)    ASPMX4.GOOGLEMAIL.COM.
    yourdomain.com.    MX (10)    ASPMX5.GOOGLEMAIL.COM.
    youripaddress / 24    PTR    yourdomain.com.

Very nice instructions, thank you.  But doesn\\\\'t this take you to iGoogle rather than partnerpage.google.com  The later is where you want to go if you have a google domain office page, right
