am sending email to the users using smtp client and MailMessage class.i have been adding the addresses of multiple receivers in the to property of the object of MailMessage class. the problem is that the receiver can see the email addresses of other receipents. is there any way to hide the email addresses of other receipents.i mean setting some property or something like that.otherwise i will be left with only option to send individual email to the users.
View 4 RepliesI've written a simple webservice and am running it locally to test it out. Right now, my settings are as follows:

Settings When Hosted Externally
<system.net>
<mailSettings>
<smtp from="noreply@domain.net">
<network host="smtpout.secureserver.net" password="<password>" port="25" userName="noreply@domain.net"/>
</smtp>
</mailSettings>

I've tried these settings, and also tried explicitly setting the properties of my SmtpClient object @ run-time. On send, I receive the following exception
"Failure sending mail. Unable to connect to the remote server - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 64.202.165.58:25"
I use a Smtp Client to email submitted information from an asp.net form. 3 users sent in their information and the user on the other end did not recieve either one of the emails. On the 2nd time around, she did recieve the emails. What could it be?

I can find loads of posts about codes to send emails using smtp, but I've got a problem. I want to send a registration mail to a user that has made a new account on my site, so he can activate it by clicking on a link in the mail. Only problem is: I need to use an smtpserver but I don't know which smtpserver i can use, so the mail is never sent!

The application sends the email without problems. The issue is that somehow a third person is enlisted in the cc, and receives a copy of the email!. What could be the problem? The smtp? IIS?
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.
View 3 RepliesI'm building a forgot password feature for my first secure backend.
I want to email a url containing an encrypted parameter to the user which will lead them to a password reset form that can only be accessed via the url with the encrypted parameter.
But what if the email gets intercepted?? then anyone who intercepts it will have the link to the reset page.
Is there a way I can send a secure email? I know nothing about email really. Is it even possible to send a secure email? Can I encrypt the email, will that help? But if it is encrypted then how does the recipient read it?
I can not send mail, this error means ?
