Using System.Web.Mail And System.Net.Mail - Error "MailMessage Is Ambiguous"
Dec 29, 2010
We have a website which we have re-designed and coded to work using System.Net.Mail but other parts of our website use System.Web.Mail We have specified the namespaces to be used in our web.config file but as we are specifying both System.Net.Mail and System.Web.Mail and they both use MailMessage it throws an error 'MailMessage' is ambiguous, imported from the namespaces or types 'System.Web.Mail, System.Net.Mail'. Is there anyway to avoid this error and still use both namespaces?

I have 3 issues that I am attempting to resolve in development with using an aspx page to send email (both internal and external).1. Using the ddl.SelectedValue for the To email address doesn't send the email to the person, but will still cc and bcc the hard-coded recipients. If I replace the(DropListVendor.SelectedValue.Trim()) withmyemail@chuckanddons.com it sends just fine. However I need my users to be able to select which vendor to email, hence the Drop Down list for Vendor. I'll post my code below.

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.
[Code]....
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.

I have a web application that is running on IIS within my company's domain, and is being accessed via intranet. I have this application sending out email based on some user actions. For example, its a scheduling application in part, so if a task is completed, an email is sent out notifying other users of that.
The problem is, the email works flawlessly in some cases, and not at all in others. I have a login.aspx page which sends out report emails when the page is loaded (its loaded once a day via windows task scheduler) - this always seems to work perfectly. I have an update page which is supposed to send email when text is entered and the "Update" button is clicked - this operation will fail most of the time. Both of these tasks use the same static overloaded method I wrote to send email using System.Net.Mail.
I have tried using gmail as my smtp server (instead of our internal one), and get the same results. I investigated whether having the local SMTP Service running makes any difference, and it doesn't seem to. Besides, since C# is server-side code, shouldn't it only matter whats running on the server, and not the client?Below is my code to send email.
public static void sendEmail(String[] recipients, String sender, String subject, String body, String[] attachments)
{
MailMessage message;[code]....

I am using System.Net.Mail in C#.net website. Basically, I use this to send email alerts to users when some action has occurred.
The problem is, when some PC's are used to trigger an email, nothing happens. I have 2 PC's in my office, and when I do the action on one of them, it works, but not on the other. Why is that?
Also, when an action is triggered by the login page (email reports), it works everywhere, but not on other pages.
I thought C# was server-side code? Shouldn't everything work or not work based on what the server has installed?

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.
