<div class="content wysiwyg-content">
I am having some e-mail delivery issues, so I added SPF records for my domain and I am still seeing issues (I am behind a static IP). Reverse DNS resolves properly, SPF Passes, and I am scoring a -.05 on assasin, so I have decided to start using Jango transactional SMTP to track delivery (they give you access to the smtp logs as well). <br />
<br />
My question is, if I set up domain keys on my domain, will emails without the key be marked as unsigned (which is how they are now) or will they be marked as fraudulent and undeliverable?<br />
<br />
The transactional emails through Jango will be signed, but individual emails from users using our ISP's smtp server will not and I want to make sure these get through.<br />
<br />
Thanks!

Setting Up Domain Keys &amp; Sending Unsigned Email

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.

Email Protocols

An email client, email reader or more formally mail user agent (MUA) is a computer program in the category of groupware environments used to access and manage a user's email. A web application that provides message management, composition, and reception functions may internally act as an email client; as a whole, it is commonly referred to as webmail. Likewise, email client may be referred to a piece of computer hardware or software whose primary or most visible role is to work as an email client. Email clients can also have other systems, like calendars, notes and contact managers.
