Web Forms :: Using System.Net.Mail To Send Email To Gmail Account From Outlook Web Server
Jul 15, 2010
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:
[Code]....
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.

The below code working fine but I dont want to pass the username and pwd at NetworkCredential. Is there any way to avoid passing username and password ? Is it mandatory that we should pass from username and password in NetworkCredential ?
SmtpClient _SmtpClient = new SmtpClient("smtp.gmail.com");
MailAddressCollection _MailAddressCollection = new MailAddressCollection();
MailMessage _message = new MailMessage();
_message.From = new MailAddress("abc@gmail.com");

Having problems sending email to a gmail account? In my web config I have it setup as:
Code:
<system.net>
<mailSettings>
<smtp from="xxxx" deliveryMethod="Network" >
<network host="smtp.xxxx.com" password="xxx" userName="xxx" enableSsl="false" port="25" />
</smtp>
</mailSettings>
</system.net>
This works if I send it to something like my domain, but if I try this to gmail it will give me something like "secure connection required" I've tried a few different ports. I've tried 587 and it gives me the same thing. If I turn enablessl=true ports 587 and 25 will tell me secure email no supported. If I try it on port 465 it will time out.
there's a thing called "Collaboration Data Objects for Windows 2000" using System.Web.Mail, but I don't want to do that because I'm using System.Net.Mail and microsoft also when I try and compile the CDO objects it says it's now unsupported plus it doesn't work anyway. It times out when I try this:
Code:
Dim smtpServer As String = "xxxx"
Dim userName As String = "xxx"
Dim password As String = "xxx"
Dim cdoBasic As Integer = 1

a couple weeks ago, my ASP.NET website stopped sending user comments which I implemented by emailing those comments to my email account through Gmail SMTP server [URL]. I opened the project on my development machine and again it fails to send the email after a couple minutes with the following exception message:
Failure sending mail
Unable to read data from the transport connection: net_io_connectionclosed.
I'm using Gmail's SMTP with port 465, and MailClient.EnableSSL = True.
The weird thing is my Office Outlook 2007 is using the same settings and it doesn't have any problems sending mail using the same Gmail account.

I am developing an web application using VB.NET in which user have to confirm the email address they provide to activate the account, in short I have to send an email for activating there account. I am all set with the logic and codes, the only trouble is I just realise that i need a mail server and domain to be able to send email.
To be honest with you all i need now is something to try if the application is working and obviously for demo. I havent got any domain yet and no intention of buying one.

I placed break poin in code and when send method is called it shows error box with heading "Smtp exception was unhandled by user code" and in detail it says "Faliur sending mail". If I continued on browser it shows error page with these details:

I have a "Contact Us" page where in users will give in their email id and a query and on submitting the form, web admin would receive that email.
If I configure their email id to "from" MailAddress and send the mail, it will fail to do so if the ID is from popular mail domains like gmail or hotmail but would work with other unpopular or non existent domains like me@abcxyzmail.om without any credentials provided!
It worked with gmail after I configured SMTP and network credentials properly. The aim is to let the admin of my website who receives the email be able to hit the reply button in his mail client and see the "to" field populated with the "from" field filled in "contact us" page. Is there any proper way to do this or a tip or trick to accomplish it.
