How to send a mail from non existing mail? Example: no-reply#mydomain.com using Spring Mail Sender Configuration. A mail doesn't exists so that reply to email address should fail.
Solution with java mail also preferred.
I tried with this too. It is not working with spring framework.
(Unknown Sender) when sending email with pdf attachment created in iText from java application
no-reply#mydomain.com
If you're not using SMTP authentication then it doesn't matter whether the email exists or not.
You can send email from addresses that doesn't exist without using SMTP authentication but that's usually a bad practice because such email's are usually evaluated as spam by most of the spam filters.
See this answer for more details.
Hence it's best practice to send email using SMTP authentication. But when sending email using that way you should have all credentials like email, password, outgoing server, port etc... and so you'll need a email that does exists.

I am a newbie in using SendGrid. I have a web application that send a mail to users after the successful registration. I am using send grid to send mails.
It works fine when I try to send Google email accounts. But when I send mails to Outlook email addresses, it always failed to deliver emails.
I checked the SendGrid 'Activity' section it shows like below.
You might need to setup domain authentication. This link should be a good place to start: https://sendgrid.com/docs/ui/account-and-settings/how-to-set-up-domain-authentication/
Outlook might have different firewall rules blocking incoming (potentially malicious) emails while GMail might have a different set of them.
I'm using the smtpclient class to send email from my asp.net website hosted on Azure in the 'shared' setup. Everywhere it says that port 25, and ALL ports are open on the Azure servers. My code works from my onw pc, but when published on Azure, it breaks. I am using gmail port 587 secure smpt and I get the error System.Net.Mail.SmtpException: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.
Any ways to get around this? (Without installing a vm with Exchange on it, like ocme on, it's a simple email message).
You are getting that error because of these two possible reasons:
You are using the SMTPClient of Gmail and you are passing the EmailId of some other website like Yahoo/Hotmail etc.
EmailId you are using is not authenticated, you need to provide your mobile number to authenticate your Email Id.
If you are using Yahoo/Hotmail then you can refer to this article which I had created on http://www.c-sharpcorner.com/

My website uses ASP.NET to send emails, but my school's network administrator has blocked the SMTP port and services. After I visited the p2p forums I found a suggestion to use web service to send email, have you any suggestion which website would provide web service for sending emails?
I tried to use System.Web.Mail.MailMessage class to send the emails through my program, but it also fail. Anyone can help me to solve this problem? I need your help. Thank you!
You can use SendGrid.
They offer a webservice and you can send up to 200 emails a day with a free account.
They have code samples for several languages: https://github.com/sendgrid
I think Email sending with ASp.net has nothing to do with blocking of your smtp port and service of school.
You can use gmail's smtp server for sening email in your application/
SMTP URL HOST : smtp.gmail.com,
IS SSL Enabled : true,
PORT: 465,
USERId:your_username#gmail.com,
Password: Your_Password
Use Gmail, Yahoo or other Email providers to send a mail.
Please refer my answer #CodeProject - sending email to gmail from asp.net, if you want to use Gmail.
Also follow - Send Email from Yahoo, Gmail, Hotmail (C#).
Well that depends, if you are talking about the SMTP port of your network, then you can still use Gmail, Yahoo, Outlook or other ports, all you will be needing will be just a username and password alongwith the port (that must be 25) and the server address (for gmail it is smtp.gmail.com).
But if you are talking about Sending emails without using SMPT. Its not possible, with or without ASP.NET.
However, you can try using SmtpSettings for ASP.NET.
There are some other issue too. Please checked that the SmtpServer that you are using (gmail, yahoo etc) are allowed, because if they are blocked too, you would have to search for something new.
And yes, there are some other servers too. Like free email providers that would also let you use 200emails/day for free or something like that. You can check that out.
You mentioned you are using System.Web.Mail.MailMessage, here is an msdn blog post about setting the Smtp for that: http://msdn.microsoft.com/en-us/library/system.web.mail.mailmessage.aspx

Sending email requires SMTP Server. If you want to use Gmail SMTP Server to send emails from localhost, you need to configure gmail user email, password and SMTP Server. Here is an article that is helpful, disucssing many ways to send emails from ASP.NET.
Sending Email using C# and ASP.Net 2.0
hi i want to send a some form entries resulting in a postback to be mailed automatically with my gmail account to the target mail id entered by the user with asp.net - c#?
You can send an email using: http://www.systemnetmail.com/
Gmail uses the mail server that you can configure (I forget the exact address, but you can find it on the google site) your web application to use when it sends mail.
As gmail lets you send mail var SMTP you should just be able to use the SmtpClient class in the .net framework.
Do you however often have to configure your virus scanner to allow out going emails from the process the Asp.net is running in.
