    <p>I'd recommend DKIM support at the MTA level so all your server generated email for a given domain is signed by default. (unless you have a really good reason to not sign all server generated email for a domain).</p> <p>The best starting point in my googling to get DKIM setup on LAMP with dkim-milter and sendmail (on CentOS 5.2 in my case) was <a href="http://www.codinghorror.com/blog/2010/04/so-youd-like-to-send-some-email-through-code.html" rel="noreferrer">Jeff Atwood's post about sending emails through code</a>.</p> <p>I would agree with him that the first 2 things you should address are reverse PTR record and DKIM signing.</p> <p>Also very important:</p> <ol start="3"> <li>IP address of the box to send email not already being blacklisted.</li> <li>make sure postmaster@emailsendingdomain.com is a valid email box</li> <li>if your server generated email needs to appear to come from somewhere else (like a contact form needing to come from name/email provided in a form) <a href="http://old.openspf.org/webgenerated.html" rel="noreferrer">follow these guidelines for email headers</a>.</li> </ol> <p>Here is the <a href="http://whatismyipaddress.com/blacklist-check" rel="noreferrer">email ip address blacklist checker</a> that I used.</p> <p>Those 5 things will solve perhaps 95% of your email deliverability issues.</p> <p>This <a href="http://allaboutlamp.com/2009/09/setup-dkim-for-postfix-in-fedora-using-dkim-milter/" rel="noreferrer">Guide for Fedora/dkim-milter/postfix</a> is also very good.</p> <p>The PHP mail library I use for my app is PHPMailer 5.1 which has DKIM support (and is PHP 5 only), but after doing the research, I decided implementing at the sendmail level was a better solution. As you can see, even the author of PHPMailer 5.1 does not suggest DKIM at the PHP mail library level is the best solution <a href="http://dkim.worxware.com/" rel="noreferrer">http://dkim.worxware.com/</a>.</p> <p>Best of luck to you.</p>

    1. COUseful info, but not for me, sorry. I'm using an external SMTP email provider and have no control over their code. I have to use them as i'm sending thousands of emails. The rest of the suggestions do not directly apply to my question.

    2. CO@Alex: I was about to code my own DKIM implementation for PHP but I'm with jigglee: the MTA should handle it. Imagine that the MTA alters / reformats the email content, there is no way for PHP to know that à priori and that would make the private/public keys to fall apart, it would have the adverse effect.

    3. COUPDATE: I have since found a better combination: postfix + opendkim. I know this still doesn't addresses Alex's issue of external SMTP provider, but I know others who find this thread searching who do have root on the mail server. [This blog post](http://blog.calmblue.net/2010/05/opendkim-postfix-centos/) is an excellent guide to set it up.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
