If you are using System.Net.Mail.MailMessage try this:
yourMailMessage.EnableSsl = true;
This could be:
Firewall related
IIS User account related
Have you tried smtp.googlemail.com Reading this it doesn't matter
I realise that's a bit of a generic answer but your config settings are correct so logically it can only be related to the network, or the user.

I am trying to send email whenever there is an exception in my code using Elmah.
Here is the configuration in web.config file.
<elmah>
<errorMail from="MyEmailId#gmail.com" to="MyEmailId#gmail.com"
async="true" smtpPort="0" useSsl="true" />
</elmah>
<system.net>
<mailSettings>
<smtp deliveryMethod ="Network">
<network host="smtp.gmail.com" port="587" userName="MyEmailId#gmail.com" password="MyEmailPassword" />
</smtp>
</mailSettings>
</system.net>
Now above configuration works fine. I tested in localhost every time I get an exception I am getting an Email Successfully.
Question 1:
Does that mean if I deploy my application with above settings, no
matter who ever access my website, if they get an exception I will
receive an email.
Question 2:
I have added password in above config file. But now everyone can see
my password. Is this the right way or I can still send the mail w/o
putting my password in config file.
Answer to question 1 :
Exceptions will be caught irrespective of the type of error module you
use. So you will definitely receive an email in those exception cases.
Answer to question 2 :
Why are you using your personal mail id? Create a new ID and use it
for the purpose, so that even if others see, it doesn't have any
effect. Others means only the developers will be able to see, not the
public. You can encrypt the web.config file by checking this MSDN
article.
Also consider encrypting your password and storing it in the
web,config file.
Exactly as it says on the tin: is it possible to specify both delivery methods in a single configuration? I'd figure it'd be a quick (and cheap) solution to log all e-mail messages that were sent directly by the standard .NET SmtpClient.
What I'm trying to achieve here is a solution in which every e-mail sent by an defaultly SmtpClient instance is both submitted directly to a configured SMTP server and stored in a pickup directory, which merely will act as a storage point for logging the sent e-mail messages.
In other words: Is a configuration as follows possible?
<system.net>
<mailSettings>
<smtp deliveryMethod="Network" from="source#domain.com">
<network host="127.0.0.1" />
</smtp>
<smtp deliveryMethod="SpecifiedPickupDirectory">
<specifiedPickupDirectory pickupDirectoryLocation="C:\SmtpLog" />
</smtp>
</mailSettings>
</system.net>
Don't believe this is possible in the manner you suggest - see Scott Gutherie's response on http://weblogs.asp.net/scottgu/archive/2005/12/10/432854.aspx (search page for "multiple SMTP servers"). Old message but still current from what I can tell.
I think the system.net mailSettings in web.config are supposed to be considered the default settings.
However you can do it in code easily enough (plenty of examples out there) and you could do it so that you can configure in web.config using custom settings.
I get this error when trying to send an email using Asp.net application using SMTP on IIS 7.5
The error is "System.Net.Mail.SmtpFailedRecipientException: Mailbox unavailable. The server response was: No such user here at System.Net.Mail.SmtpTransport.SendMail(... "
What i have in web.config is
<system.net>
<mailSettings>
<smtp from="support#mysite.com" deliveryMethod="Network">
<network host="hostname" port="25" password="password" userName="you#yoursite.com" />
</smtp>
</mailSettings>
</system.net>
I really don't understand what should be the username and password here. I get the same error when i put defaultcredentials = "true" instead of username and password. Is there something to do with toaddress. The toaddress is myid#mydomain.com, which works for all other emails, etc.
Please advice me where i am doing wrong!! Thank you in advance!
The userName and password settings refer to the credentials for connecting to the SMTP server. Make sure you don't confuse this with the username and password for the from or to address, which is not relevant to the SMTP server.
You may want to try a tool like SMTPDiag to help you figure out any SMTP connectivity issues you have. However, your error seems to indicate that connectivity is fine but that mail cannot be delivered.
Ram if you are using a web host and you have SMTP support in your package... Then check their control panel.
Also as Jacob I want to remind you that FREE SMTP user accounts that web hosts offer are different from credentials to connect to the SMTP server itself. Usually the former is that's free with web hosts and the latter is not included as long as you don't have a dedicated server I think.
If you don't find it in their control panel then call support... They will be able to give you those details if applicable.
When trying to send out an email in a .NET site, the following error is being encountered:
Mailbox unavailable. The server response was: No such user here
Does this error appear if the code is trying to send to an email address which doesn't exist?
Thanks.
I now have more information about this error. The emails are sent from 'noreply#[domain]'. When the emails are sent to an email address of the same domain, the emails are sent without a problem. This error only appears when the email addresses being sent to are not from the same domain. I don't know if that's any use?
This happens when you specify a domain with your NetworkCredentials. If you specify a domain (third argument) then you can only send to valid mailboxes within that domain. Leave it out to be able to send to any address outside the domain.
var client = new SmtpClient("smtp.server.com");
client.UseDefaultCredentials = false;
// The following will be able to send to anyone outside the domain.
client.Credentials = new NetworkCredential("user", "password");
// The following will only work when sending to users on server.com
client.Credentials = new NetworkCredential("user", "password", "server.com");
Could be that your password is incorrect. I had to reset the password on the mail server, then the error went away.
This may happen when you switch from 2.0 platform to 4.0. As it was explained here you need to tell IIS explicitly that you are not using default credentials and domain. Use the following syntax in web.config:
<network host="mail.younameit.com" port="25"
userName="account#younameit.com" password="youchoose"
defaultCredentials="false" clientDomain=""/>
The last two parameters are most important to fix this problem.
This sounds like an smtp issue
Try setting your smtp server info in the web.config file like this :
<system.net>
<mailSettings>
<smtp deliveryMethod="Network">
<network defaultCredentials="false" host="mail.blah.com" password="xxxx" port="25" userName="ex#blah.com"/>
</smtp>
</mailSettings>
</system.net>
This is a decent article detailing this section of the web.config and how to access it with code behind :

This Q/A was useful to me in a similar situation. For us, the key fact was that the error only occurred for email addresses on a different domain. I learned that our new webhost/mail server setup is intentionally configured this way. (A previous one with the same hosting co. was not.) Some combination of app code or Web.config settings might have solved our problem, but the most direct way forward was to create a no-reply account on our domain, so that now no-reply#ourdomain.com IS valid, and IS allowed to send to external addresses.
No modifications to code or the Web.config were needed. The latter calls out only "from" and "host" and the credentials are not needed in our hosting environment. (When we override the nominal "from", we need to override it to be some other address that's valid on our domain.
I'm trying to send email via google apps from my asp.net app and am getting the following 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 "}
My Web.config has the following values (sorry I couldn't get the XML to display):
<system.net>
<mailSettings>
<smtp from="user#domain.com"
deliveryMethod="Network">
<network host="smtp.gmail.com"
port="587"
userName="user#domain.com"
password="password"
enableSsl="true"/>
</smtp>
</mailSettings>
</system.net>
I'm thinking that this is due to my not having an SSL cert but I'm not sure. Any thoughts?
I have it working this way with one of our gmail account (code is simplified):
SmtpClient client = new SmtpClient("smtp.gmail.com", "smtp.gmail.com");
client.EnableSsl = true;
client.Credentials = new NetworkCredential(userName, userPassword);
client.Send(mail); // mail is of type System.Net.Mail.MailMessage
You could try to send an email with this code and your configuration just to see if you receive the same error message.
Your code should work fine; I use the exact same configuration successfully.
You may have a firewall issue.
