What doesn't work?  Can you subscribe to the newsletter?  Are emails just not going out?

ı am addinng email address but when ı add a new post its not sending email

I had the same problem. Make sure your SMTP server allows relay from your web server. This was causing mine to not work. No error would be displayed. I had to debug into the SendMailMessage method in Utils.cs (BlogEngine.Core project). I was able to see the message about relay not being allowed when hovering over the SmtpException line. Enabling relay will vary from server to server, so check Google for yours.

When the newsletter emails are not sent, are you creating new blog posts, or editing existing blog posts?

The newsletter widget that comes with BE 1.5 will only send the newsletter emails when you're saving a new blog post, and the blog post is marked as "published".  If it is initially unpublished, and you later go back to publish it, the newsletter emails won't be sent out.

This behavior was changed after BE 1.5 was released.  You can try using the latest version of the Newsletter widget.  The only file that I believe changed was the Widget.ascx.cs file in the Widgets\Newsletter folder.  The latest version of that file is at:

You can try replacing the content of your Widget.aspx.cs file (in the Widget\Newsletters folder) with the content at the link above.

The main difference with the latest version is that the emails will be sent out whenever the blog post is going from an unpublished state to a published state.  So if you initially save the blog post as unpublished (to see how it looks, for example), and then later go back in to 'Publish it', even in this scenario, the newsletter emails will be sent out.

You can download the latest version of BE on the Source Code tab above.  You'll need Visual Studio to compile the BE core project.

However, the latest version only has the added feature of sending newsletters when a post is going from an unpublished state to an published state.

With BE 1.5, if you create a new post and that post is marked as published, and the emails do not get sent out, then I don't believe the latest build of BE is going to make a difference.

With BE 1.5, if you create a new post and that post is published, do the Newsletter emails get sent out?

How many people are on your email list, btw?

Have you checked the newsletter.xml file in the App_Data folder?   Is that where you see the 5 email addresses?

Jul 18, 2009 at 11:48 AM

Does the Test email work on the Settings tab in the control panel?

How about the Contact page?  Does that work?

Jul 18, 2009 at 12:00 PM
yes it si working ı tested ı ı get success message yes contact also working ı send too many test message only problem in newsetler if you want ı can sen you my newsetler widget

If your newsletter widget hasn't been changed since 1.5 was released, then I'm guessing it's okay.  You can post the contents of the widget.ascx.cs file here if you'd like.

One thing you can try is re-starting your blog application.  You can restart it by making any change in the web.config file (add a space in it, etc).  The newsletter email addresses are cached in memory.  Although it's doubtful, there could be a problem with the email addresses in memory.  If you re-start the blog application, BE will re-read the newsletters.xml file -- getting the latest version of that file.

now it is ok but this time it is sending only one adress it is not sending email to windowslive or gmail it is sending mail only my domains mail
Jul 18, 2009 at 11:09 PM

If it's only sending email to the same domain name that you're using for the From address (i.e. to, that could be because of misconfigured email settings on the Settings tab in the control panel.

I would review the email settings you have in there.  I've seen before where if you are using an invalid Username/Password (for SMTP authentication), then a mail server might deliver intra-domain email, but not deliver email outside of the server.

You can ask the support department at your web hosting company what SMTP settings you should be using -- SMTP server name, Port Number, SMTP Auth Username, SMTP Auth Password, Enable SSL.

BENAMANDA THANK YOU FOR YOUR HELP . in monday ı will contact my hosting company to solve my email problem.
Nov 9, 2009 at 1:46 AM

I am having athe same problem.  with 1.5.  In 1.4.7 it worked fine but now it will only send to same domain addresses.  My list is small and the settings are the same for the smtp host. 

Also it would not send comments nor comment notifications to admin nor to users for replies.  I got the comments working by reading a different post. 

I seen another post about comments and credentials and made the change the suggested and got the admin comment notification but I do not have user notification for replies.  Tomorrow I will be doing another post and see if anything changed there. 

Now my host does not require credentials if I am sending it from the the web server to the mail server.  I added credentials to get the above checnge to work because after looking at the code I realized that it only took place if there were credentials. Later I will try to move the fix to outside the if statement and remove my credentials and see if I still have that part.  But so far I have not seen a new post email to a non-domain address from ver 1.5
