Configuration :: Email Web Form Is Blocked From Gmail?
Mar 13, 2011
I have a web form that will send a message fine to every email address other than gmail (this one I know for sure) the message is " Delivery to the following recipients failed. " I know this email works since it is mine. I have my own e-mail server and when I send to the same gmail account the message goes through fine (using the same e-mail address in for form and in the e-mail client). Is there some coding I need to add to prevent this form message from being blocked?
I am trying to send email from my asp .net code ,it is sending email to email ids except gmail.com. all mails with gmail.com is going into my Badmail folder in inet pub folder in my local system.
SmtpClient client = new SmtpClient(); client.Host = "mail.abc.com"; client.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis; client.Credentials = new System.Net.NetworkCredential("ab", "rr"); client.Port = 25; string to = "arvind.abes@gmail.com"; string from = "rvsales@westrvwholesaler.com"; MailMessage mail = new MailMessage(from, to); mail.Subject = "hello......?"; mail.IsBodyHtml = true; mail.Body = "hi, how are you?may be this will work"; mail.Priority = MailPriority.High; //client.EnableSsl = true; try { client.Send(mail); } catch (Exception ex) { Exception ex2 = ex; string errorMessage = string.Empty; while (ex2 != null) { errorMessage += ex2.ToString(); ex2 = ex2.InnerException; } Response.Write(ex2.Message); } mail.Dispose();
Sometimes I would like to be able to update during day time my ASP .Net application. I noticed that quite often updating DAL's (.xsd files) that are in used will block my application (and users). The only way, I found to recover, is to restart IIS but my users do not like it.
Is there some more clean way to update an online server without disrupting the users ?
Could I identified the DAL which are in used and the users using them, so that I could somehow disconnect only these users (My application uses Windows authentication).
while send email from asp.net code, When i am sending mail to other than gmail then its work fine , but when i try to send an email to gmail account its not working Send To : info@[URL] is my gmail account email address When i send email to info@[URL] its not working when i use another email Like Send To: awakeel@[URL] its work fine and i recieve the email
We have a business web application that periodically sends emails as reminders, links to client data, etc. Our company uses Google Apps for our email provider (with our own domain name), and the web application sends email through Google with SMTP.
The problem is that Google Apps / Gmail keeps marking the messages as spam, even for the inboxes in our domain name. No other email provider seems to mark it as spam (but of course we haven't tested them all...).
We've tried various formulations of the body test: i.e. including more contextual information, addressing the recipient by name, but so far with no apparent changes. This makes me thing it may be something about our email sending process, rather than the content of the email, that's causing the emails to be marked as spam.
Things that we tried but that didn't solve the problem:
"From" address is valid and not spoofed SPF records are correct, and show as "pass" in the email header Since we are connecting to Google's SMTP server to send email, it's not an issue with a blacklisted IP address (however, our website has a static IP address that is not blacklisted). Email is not very spammy: I've checked against several online spam filter tests, and the email body always shows up as extremely unlikely to be filtered. HTML body vs plain-text body seems to make no difference. We send a small volume of email: probably 0-10 emails per day, so I don't see how that would make this suspicious. Whenever we have access to the receiving inbox (i.e. it belongs to an employee of our company), we've been marking the emails as "not spam", since Gmail may be using communal statistics to determine spam. After a couple times this results in emails to that particular inbox getting through, but doesn't seem to help other accounts.
What else can we try?
If it makes a difference, we're sending emails using an ASP.NET site running .NET 3.5. A typical email gets sent like this:
var message = new MailMessage(new MailAddress(from), new MailAddress(to)) { Subject = subject, Body = body IsBodyHtml = true }; // SMTP details stored in web.config new SmtpClient { EnableSsl = true }.SendAsync(message, null);
EDIT: I've seen this similar question: How to stop Gmail from marking mails sent by my web app as spam?, but the situation is a little different since we can reproduce it by sending and receiving from the same Google Apps domain. Besides, I believe I have covered all of the proposed solutions for that question.
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
I am using gmail in my asp.net site to send email. It is working fine on shared server but it donot send email when I run my site on local machine in visual studio. Please guide what should I do to make it sending emails from local machine as well.below is my code:

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"
TL;DR - Any webapp devs out there able to squeeze performance out of using gmail as SMTP server without a 3-10 minute delay to delivery?I'm looking for some feedback from developers who are using gmail as a secure SMTP server for use with Webapps.Within the past 2 weeks, my company has switched to gmail to host email for our domains.I have a few webapps that send from our ISP server, but I'd like to refactor the code to use gmail with our domain name. I know the ISP can rig things up, but I don't want relay issues.I have gmail sending for the Webapps and it's more or less working. On ASP/IIS, I'm using SSL and on PHP Linux, I'm using TLS.It seems that TLS (port 587) works better than plain old SSL (port 465), but the overall performance difference seems minimal.What concerns me is that there is often a significant delay (10-20 minutes at times) to get email to a recipient no matter which method I use to send via gmail.While I understand this can happen in any environment, I am used to fast delivery. Use case is salespeople talking to customers and needing to get email to them very quickly using the Webapp. Before the gmail switch, usually less than a minute to deliver. Now, it is 3-4 minutes minimum.Am I crazy to try to use gmail for this purpose? There seem to be a lot of devs using it, so just wanting to know how it works out for them/you.
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 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. Exception Details: System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host
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 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"
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?
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;
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 want to make a email service project like gmail, yahoo with small feature. I am unable to understand from where i start it. Can you provide me the complete detail to start this project.
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 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.
