I ran into a little stumbling block while trying to setup Google Apps gMail with a domain at one company and web hosting at another. In my case, a domain with GoDaddy and hosting with HostGator.

The instructions Google provides are quite simple. All you need to do is update the MX records for your domain with the following:

• ASPMX.L.GOOGLE.COM. (Priority: 10)
• ALT1.ASPMX.L.GOOGLE.COM. (Priority: 20)
• ALT2.ASPMX.L.GOOGLE.COM. (Priority: 20)
• ASPMX2.GOOGLEMAIL.COM. (Priority: 30)
• ASPMX3.GOOGLEMAIL.COM. (Priority: 30)
• ASPMX4.GOOGLEMAIL.COM. (Priority: 30)
• ASPMX5.GOOGLEMAIL.COM. (Priority: 30)

GoDaddy even provides a wizard [dead] to do this, which is where things can go wrong. The wizard only works if you have your domain's DNS hosted with goDaddy. If you have your Name Servers pointing elsewhere, like your hosting provider, your MX records will remain unchanged and google apps setup will continue to report "Updating (May take upto 48 hours)" indefinitely.

Instead, you need to update the MX records at wherever your Name Servers are pointing. Most likely in your hosting company's control panel. It makes perfect sense, but if you're doing things in a hurry it's easy to make the mistake.

Suppose we want to format digits with commas after the 2nd and 5th digits.
Ie. Convert 12345678 to 12,345,678

Using substr, perl's substring method, this is achieved with:

$old = ‘12345678’
$new = substr( $old, 0, 2 ) . ',' . substr( $old, 2, 3 ) . ',' . substr( $old, 5, 3 );
# result: 123,456,78

It works and it’s fine, but perl critic will complain about the use of the numbers 0,2,3 and 5. You could go ahead define them as constants, but that’s cumbersome for trivial substr parameters.

Using a regular expression provides another option.

$old = ‘12345678’
$old =~ m/([d]{2})([d]{3})([d]{3})/;
$new .= $1 . ',' . $2 . ',' . $3;
#result: 123,456,78

It’s easily readable to anyone looking at your code and best of all perl critic won’t complain about it.
