Getting 554 Denied Error when sending an email message

If you get this error it means the message failed permanently, at the receivers server normally it will generate a bounce bounce back to the sender....and will not be re-delivered or re-tried.
example:

554 Denied - Denied for Spam Content

Solution:

If you believe that the message is legitimate and should be delivered, contact the recipient and let them know what you are seeing and request that they Whitelist / Allow your sending address.

Why this happens? 
Although any spam filtering, Firewall or Mail Server can reply with a similar type of error this normally happens when the recipients server is using some type of spam filtering service.

Here are some of the common Spam Filtering service that are know to send back a 554 Denied

TIP: In some cases if you get 554 Denied "RELAY is NOT ALLOWED" then the issue is actually on the sending end normally means that when you try to send the message the sending server didn't trust your message and bounced it back, this normally happens if your IP or Domain is not recognized by the sending server as valid. 

Directorypress Details page display / adding map location

One of the biggest issues I had with the Directorypress template is editing the details page.

I wanted the map location (map_location) to display on the details page.
I searched for sometime for an answer on the best way to get this done and finally came across this http://www.premiumpress.com/forums/topic/address-for-map-location-on-add-listing-form In the directory press forums.

The page that you need to edit is called _single.php
(_single.php)  found under Admin > appearance > 

Then you can add the following code to display any field or custom field: 

<?php echo get_post_meta($post->ID, "map_location", true); ?> 

you can replace "map_location" with any other field you would like to display, I actually added this code above the listing and also next to the Google map to display the address. To see how this looks on my directory press details page visit: http://georgiahealthcareprofessionals.com

I also went a little further and used the code from a Google gadget that get's directions and also added that to my _single.php page.
