Here is a notes for Email Server Settings. It is not just for Email server. It is mainly for DNS setting for Email server.
The purpose of it is to prevent from your outgoing email into spam box.
I have a web page, which use PHPMailer to send email. The problem of it is most of time the recipient found the email in the spam box. I am using sendmail to send out email.
Later I choose to use ZOHO as my email service provider. And choose smtp in PHPMailer.
So, the solution is here for ZOHO.
I mentioned before, I use Google Apps for your domain as one email service of my sites.
Email service switch is very smooth.
And user interface is same as Gmail, friendly.
One issue found. I send an email to an email address ended by 163.com.
The Delivery Status Notification (Failure) message said:
Technical details of permanent failure:
PERM_FAILURE: SMTP Error (state 8): 550 MI:SPF mx20,wKjR5bDbf6h9JaNFxfU9DA==.29331S5 1168320069 http://mail.163.com/help/help_spam_16.htm

How do I set my SPF records?
Sender Policy Framework (SPF) records allow domain owners to specify which hosts are permitted to send email on behalf of their domains, making it hard to forge From: addresses.

To set your domain’s SPF record, publish the following TXT record on the DNS resource: v=spf1 include:aspmx.googlemail.com ~all.

If you have your own email server like me, you may need to know something about SPF record.
From the SPF website, I got the following description:
SPF fights return-path address forgery and makes it easier to identify spoofs.
Domain owners identify sending mail servers in DNS.
SMTP receivers verify the envelope sender address against this information, and can distinguish authentic messages from forgeries before any message data is transmitted.
Use DNS Stuff‘s DNS report tool, you can see if your email server has a SPF record.
