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'm having problems with the "From". No matter what i put in, it is always getting filled out with whatever account i'm using to log into the smtp services. Here is the code.. not sure what i'm doing wrong by the examples I've looked at.
I've checked my mFrom property and it has the correct email address i'm trying to send it from.. Is the from just always filled out with the info that the email is sent from
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()) firstname.lastname@example.org 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.
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.
I'm trying to add an attachment to an e-mail which I'm sending out, but the attaching part doesn't appear to be working properly since I do not receive the attachment. Anyone know why this is occuring? No exceptions are being thrown. I am sending the
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.
I have this code up in a live windows 2003 sp2 server. I use Hmailserver as mail server and I am not sure if this cause the problem.I am able to send email consecutively 2 time no problem, but it is always the 3rd time after I would get this error: Unable to read data from the transport connection: net_io_connectionclosed. I wait for 30 minutes I am to send email again, but only the first 2 time works. Here is my code can someone please verify my code and see if anything is wrong with it.
I've been getting the following exception when trying to send an e-mail using System.Net.Mail:
Unhandled exception in Service Thread:

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.
