Configuration - Multiple SMTP Servers Or Update The SMTP Object Server Information At Runtime?
Nov 5, 2010
The question: Is it possible to configure multiple SMTP servers or update the SMTP object server information at runtime?
Description of problem: The site I'm working on has a few pages which send emails. Our site is using Gmail so even though it's a custom domain our email is sent out though Gmail SMTP servers.
Some emails come from the system and some emails come from users in certain groups. I have an SMTP server configured with the admin email for the system e.g. firstname.lastname@example.org This works fine and when I get the email it shows from email@example.comOne of our user groups let's call it "groupA" has an email configured on our domain i.e. groupA@mysite.com When I send the email and specify a from address for the MailMessage object as groupA@mysite.com it still shows up in my outlook as coming from firstname.lastname@example.org I did a little further testing and if I specify both the from address and the ReplyTo as groupA@mysite.com it will show as Fromemail@example.com but when I choose reply in outlook it shows groupA@mysite.com My best guess is that Gmail is overwriting the From address with the SMTP user to prevent email spoofing.
I found this: http://www.systemnetmail.com/faq/4.1.aspx but it won't work for me since group A, B, and C all need to send emails from the same page.
in my application when client completes its shopping email will goes to user this works fine when there is internet connection is working fine, if there is some problem in internet connection if one mail stops then all the mails will be stopped even now internet works fine,
how to resend the emails using smtp server, is there any option to resend the emails automatically when internet works fine.
I'm using one XP with SP 2 as my local Laptop PC . Its IIS has one default web site, of course, which is the site I'm working on. When some feature is finished I deploy it to my "production" site which is hosted somewhere else. Very common situation, I guess. This app uses email to notify customers of some particular events. Works on production, but sometimes I need to change something in the way those notifications work. Currently I have to upload the changes to "production" to check it out. Is there any way for me to set up smtp server on my local machine so I could work locally with those features?
I want some tips regarding sending mail ,I want to send bulk mail from my web application in c#. so ,what should be the best code for this and also what should be the best configuration used in the smtp server. because my current system fails to send 100 mails out of 400 mails in smtp server. I aslo used theading for sending this mail in batch of 30 mails in every 20 minute but it is not working . I want solution of both in my c# code and smtp and also is there any new solution in new technology like web services or any other option .

i am working on a personal website, so obviously it's not a company website which have exchange server or anything like that
I know how to setup SMTP but what details should i give for SMTP service ? i mean my yahoo/hotmail/gmail account will work, setting up SMTP is really important for the website i am working on to recieve and send e-mail how to do that for a personal website when there is no exchange server ?
i need to encrypt the SMTP settings for my web site, i tryed the aspnet_regiis.exe pe... but i got an error this is not a valid virtual dir. i have the website on the C drive on my development machine, i have encrypted the connectionsettings via .net code but cant finde a solution for the smtp node can i encrypt the smtp in development pc or it hacse to be deployed first?
I'm having trouble sending messages through ASP. I'm using the same settings I'm using on another Web App sitting on the same server in the same network, and trying to send through the same Exchange Server.
They work fine for the one app, but the other app gives me a relay error. Could this be because I'm using it on a separate domain? The one that works is "visitmychurch.tv" the other is "insidehcc.com".
I have a script that send a daily email to a list of recipients from a database. I am having a couple of emails failing to send and the try/catch/ex.message & ex.stacktrace doesn't give me enough information to show what the actual problem is. I have tried to do some smtp session logging but that seems to not be doable since I am running under Medium trust. Is their either another way to get this code to work on medium trust or another way to get detailed SMTP log info.
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 188.8.131.52:25"
I've been running a customer's webapplication using automatically generated email for some time, being hosted on our company's web server. Send mail was done using the System.Net.Mail API using a 3rd party SMTP server. The configuration has been done in the web.config in the system.net section, something like this:
Everything worked fine until we had to migrate to another hosting service; since then, send mail didn't work any longer with symtomatic "timeout" exceptions. We also tried using gmail and changing/omitting explicit port number specification, without any success. The server is running IIS 6 (Windows Server 2003 R2).
I am trying to get the SMTP Server in IIS7 working so I can use the asp:PasswordRecovery component. I have included a screenshot of my SMTP setup in IIS, the SMTP setup in my web.config file, and my asp:PasswordRecovery component code. I have set it up to not require any authentication settings. I basically want to specify whatever email address I want as the "From" attribute (I'm using a series of noreply* addresses for a web app), like the php mail function that lets you put whatever you want in the from argument. What am I missing? Do I need to install anything else? I'm assuming that when people say "you need an SMTP server to send mail", this is what they're talking about.
I have IIS 7 windows server 2008 R2 64 bit on which I have few web sites which are sending emails thorugh asp.net. Each web site has seperate "From Address (used inside the code)".
In IIS 6.0 mananger >> Delivery Tab >> Out bound security >>I gave Integrated windows authentication for one account (Let us say abc).
When the emails are firing from different applications, the emails are going only if the from address is abc mentioned in the authentication. If any other email address is used then it is going to bad mail folder saying "Diagnostic-Code: smtp;550 5.7.1 Client does not have permissions to send as this sender".So to make it work I have changed the authentication to anonymous then again the emails are going to bad mail with "Diagnostic-Code: smtp;530 5.7.1 Client was not authenticated" error.
module thats available for asp.net that uses a queue to send email to an smtp server? the queue being the operative word here.. we need a proper fallback mechanism for storing any messages that can't be sent so that the send can be re-attempted later
I hope you can answer the following question for me. I have a server with win 2008 installed and a simple asp.net application that is successfully sending a email through System.Net.Mail.Smtpclient("localhost").Now my 1st question is, how exactly is this mail sent if there is no Default Smtp Virtual Server installed?Next question...I get an error when I try to send an email that is larger than around 4MB. I know this is to do with the limit that is specified on the server but where is this limit set?
Third Question...fter installing a new Smtp Virtual Server #1 in the IIS6 console, I am able to see and change the file size limit on email but I cannot work out for the life of me how to send emails from my asp.net application through this smtp virtual server.Obviously the best fix for me would be to work out where the default smtp server is and how to manage it rather than installing another one and then trying to route all applications through this new virtual server.When I think I set it all up correctly I get the old "Mailbox unavailable. The server response was: 5.7.1 Unable to relay for (email address)", ie I have given my new virtual smtp server a unique ip and port number and changed the Smtp E-mail page within IIS to point to this new server.
