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.
Previously I had thread Send Mail? That helps me to send mail through Gmail credential account. Now I want to send Email through my server (suppose my server name is [URL]) so what should I do?
The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn more at
I am trying hard from the past 2 days to Send mail to my gmail account. But I am not able to do so
Only Exception i am getting is "Failure sending mail."
If i am giving wrong username and password then it is giving the exception
" The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn more at"
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");
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.
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"
Can we send email form local host using gmail smtp? I am trying and getting error The operation has timed out. I am trying to send email from local host from last 3 days. It works fine if I send emails from my hosting server using gmail but it is not working on localhost. I have disabled firewall anti virus but even then unlucky. have u ever used gmail for sending emails from localhost (without any server involved) If it is possible.
I have written the following code for sending mail.But i am getting error as failure sending mail.I can send mail when the network host is smtp.gmail.com.Heres the code
MailMessage mm = new MailMessage(); mm.From = new MailAddress(ConfigurationManager.AppSettings["Email"].ToString()); mm.To.Add(new MailAddress("gopikshnan@gmail.com")); mm.Subject = Subject; mm.Body = Body;
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;....

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.
try { using (MailMessage mm = new MailMessage()) { mm.Subject = "Account Activation"; string body = "Hello"; mm.From = new MailAddress("support@foodtrove.in"); body += "<br /><br />Please click the following link to activate your account";

I want to send mail from user gmail account using OAuth to all user contacts.It's easy to get all contacts of user with google API, but i cant send email to these contacts from user gmail account without request his password.
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.

in my asp.net application, I am trying to upload email from outlook of my account. I get the error mentioned below.
[System.Web.Services.Protocols.SoapException] = {"The server to which the application is connected cannot impersonate the requested user due to insufficient permission."}
I have to create a page in C# where i have to call a column from sql which has email addresses and on button click it should whatever mail account a user wants to use to send a mail to all users.
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.
