C# - Couldn't Send Email Using Gmail Account
Mar 16, 2011
Can we use gmail account to send email in asp.net website from *localhost * (local machine) ? I am trying but badly unsuccessful. It works fine on hosting but donot work on my machine.
I have windows server 2003 on my machine, I have added port 587 and 465 in firewall in exceptions. In my gmail account I also have enabled POP and IMAP. Some people to use port 465 and others say port 587 should be used. I tried both and below was my result:
Using port 465 it take time and finally give message that the opration has timed out. falure
Using port 587 it dont take time, show message "failuer sending email" with an inner expection "No connection could be made because the target machine actively refused it 72.14.213.109:587"
[code]....

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

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");

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.

I am using gmail for sending email in my asp.net application. Email works fine if I send email on server but if I try to send emails on local machine it give error. 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:
An existing connection was forcibly closed by the remote host Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I have configured gmail's free smtp server for my web app and previously I was using smtp server configured at the server.
So I have changed my smtp settings accordingly but my app isn't sending any email and giving me error connection time out, third party tool isn't responding after many retrials.
Here are my settings-
SmtpClient smtpClient = new SmtpClient("mail.MyWebsiteDomainName.com", 25);
smtpClient.Credentials = new System.Net.NetworkCredential("info@MyWebsiteDomainName.com", "myIDPassword");
smtpClient.UseDefaultCredentials = true;....

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.

Working from home on an XP Machine, trying to configure IIS to send emails from Asp.Net via my broadband provider (BT).
Relay 127.0.0.1 enabled, so now errors are:The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.3 Client was not authenticated
Pertinent settings that I can see are (in IIS Default SMTP Virtual Server properties):
Access, Authentication (presumably app to IIS): Basic + Integrated Windows
(However Basic includes correct BT server smtp.btconnect.com -> suggests this is authentication relevant IIS to BT, not app to IIS)
Access, Relay: 127.0.0.1 added
Delivery, Outbound Security: (presumably IIS to BT) Basic Authentication
UserName: my.btusername@btconnect.com (tried with and without @domain)
Password: ***** per my account at Bt
Integrated Windows Authentication disabled
TLS Encryption NOT selected
---
I cannot see any other obvious candidates for authentication.
I presume model is Asp.Net App -> IIS (step 1) and IIS -> BT (step 2)
I presume Access, Authentication specifies step 1, and Delivery, Outbound Security handles step 2 - though why then does IIS recognise my bt server in step 1?
