I created a web form to send emails and using a class to perform the task. The process works well for all internal email addresses but will not deliver to external email addresses. I am not sure if I missed something in the code to send to external address.
I run a Exchange 2010 server and created an account for one of my websites to send e-mails.
The webserver's IP is even listed on the [Organization Configuration] -> [Hub Transport] -> [Global Settings] -> [Transport Settings] -> [Message Delivery] list.
The code sets a set of Network Credentials, but setting incorrect or correct settings, it doesn't matter; if I list external e-mail addresses, I get a "Mailbox unavailable. The server response was: 5.7.1 Unable to relay for <address>" message, 'local' addresses that are cc-ed, do get delivered...
When checking with telnet, I noticed that the only AUTH option was AUTH NTLM, but when checking the NetworkCredentails, it stated that NTLM should would.

I am creating a bulk email sending facility for our website.I have got all the email in one table so i know i can use email sending features with one loop that take all the emails from the table and send it to everybody.I would like to give them a link that will opt out them from the list.If anybody has done it recently or know any link please suggest it.
VWD 2008 Express. Visual Basic. I use the following routine (XXXXX have replaced sensitive data) to try to send an email message to mutiple email addresses. It only sends to the first email address in the comma-delimited list. How can I send the message to multiple email addresses?
I've built several websites on my local machine and have successfully tested sending mail from within the application, but suddenly the mail won't go anywhere! I have a try-catch routine, and I'm getting the message that the mail has been sent successfully but it's not going anywhere. This is the code that I've used in a test page - the html page has a button and a textbox and nothing else. I've imported the system.net.mail namespace.
I'm getting the 'Email Successfully Sent' Message but I'm not receiving the email. I don't think I've changed any settings to stop the emails from going.
my first code below works, but my second doesnt do anything.obivously the first code just posts the html as text, but the second code does absolutley nothing at all, no errors, nothing, just no mail at all :S
Anyone know how to do this? Using my own mail server is easy, but in case there's something wrong with it or it ends up on some blacklist, I would like to use the receiver's mail server. There will only be one to: for each mail (it's a validation function to a sign-up).
I'm using this code for sending mail message for invite a friend, And I'm getting this error that I do not understand why Value cannot be null. Parameter name: from (I do have a from parameter as far as I understand )
I am trying to send an email from our web server to a gmail account via System.Net.Mail but am failing miserably receiving this error message:
Mailbox name not allowed. The server response was:
that domain isn't in my list of allowed rcpthosts (#5.7.1) Using this code I am able to send emails to other email addresses on our Outlook email server:
So I know I am capable of sending email to Gmail with port 587 and using the proper credentials of my own Gmail account. That is not the problem.
The problem is I want to be able to have the mail sent from my application from whatever the user puts in the FROM (Email address): text box to a Gmail account. When I use the above code, the address that the email is sent from is my own.
So the question is: Is there any way to configure this to be able to send from an Outlook email server to a Gmail account without having to use my Gmail account to actually do it (using my credientials). Therefore showing the email as sent from whatever the user puts in the txtEmail text box, and having it sent from the Outlook server?
I know my SMTP uses the port 25 for outgoing mail and I am pretty sure that the Gmail settings block port 25 for incoming mail, which makes sense, but what doesnt make sense is I can compose a message in Outlook and send it to a gmail account, but I cannot automate this through my programming, which makes me feel certain its my programming.
I am sending Email from SMTP server and all my Emails are landed in Junk in Hotmail ,Live and Yahoo. I am not using any Spam like content and following all the guildline to send Emails.
I check on mail to identify the Issues and found quite a few issues below
1) HELO Greeting Check
Description: Email Server HELO is . HELO greeting does not contain a valid domain. We would recommend to have a valid domain in HELO greeting. Ideally HELO greeting should be the same as Email server host name (in FQDN format).
2) BATV (Bounce Address Tag Validation) Check
Description: Email server is not using BATV format while sending out emails. BATV is recommended to ensure that your users do not become a victim of bounce floods.
3) DKIM (Domain Keys Identified Mail) Check
Description: Email does not contain any DKIM/Domain Keys Signature and the published Domain Keys policy rejects such unsigned emails. Therefore it is very likely that your emails are considered SPAM by Email servers verifying Domain keys. Signing your Outbound emails as per your Domain Keys policy will minimize chances of your Email being considered as SPAM.
