google app email server setup

If you use a hosting company and use gmail app, in order to receive email correctly, you need to do two things:

1. set MX record of your domain to gmail app, see <creating mx records> at gmail app help. The current mx records are:

Priority	Mail server
1	ASPMX.L.GOOGLE.COM
5	ALT1.ASPMX.L.GOOGLE.COM
5	ALT2.ASPMX.L.GOOGLE.COM
10	ASPMX2.GOOGLEMAIL.COM
10	ASPMX3.GOOGLEMAIL.COM

2. create SPF record, i.e.  a 'TXT' entry on your domain DNS, with value as:
"v=spf1 include:_spf.google.com ~all"

The second thing is to prevent spam. It is required by google app, otherwise you mail will be bounced.
