I'm allowing users to manage a distribution list stored in a database. Users are only allowed to enter emails that are @mydomain.com. A web based application then takes the distribution list and sends emails. I'd like to validate that the email is valid before sending an email from the application.
To send an email I'm using this code:
Dim SendTo As String = "ThisIsNotARealEmailAddress@mydomain.com"
Dim SentFrom As String = "me@mydomain.com"
Dim MessageBody As String = "blah blah blah"
[Code]....
Is there anyway to validate the email when the email address is added to the database, instead of a try catch block when sending the email?

I use this code to send an email through gmail account but the thing I want to do is, I want to check whether the given email and password exists or not and if it exists then pop out a text box with the body of the mail and type the text and then send it as a mail. But in the above code you have to log in and type body and when you send the mail , It verifies for the email and password while sending and if anything goes wrong says there is no such gmail account.but i want to check it whether the email and password exists or not, when the user enters the email and password at the beginning itself.So that he enters the right email to log on to compose a mail.Is there any way to check whether the given email and password is correct at the beginning only ?
6 program to VB .NET 2008 that had code that used the CDO 1.21 DLL to validate if a mailbox entered existed on an Exchange server. I saw the one posting from Microsoft that states that CDO is not supported on the .NET Framework. As this is a client application, the article recommended using WebDav to interact with the Exchange Server.
I was wondering how i would be able to validate a textbox for the E-MAIL address of a person. For example it cant have anything like "`#[]-=+->~| etc. it MUST have an @ and a .com or .co.uk at the end of the e-mail. anyway i was wondering how i would be able to program this when the user types into the textbox they cant put in any of the other symbols?and IF there is a missing @ or .com then the user should receive an error message telling them to make sure that they put them in.how would i program that on a button?
I am using this regex string in one of my programs to validate email adresses: "^[a-z0-9._%+-]+@[a-z0-9.-]+.[a-z]{2,4}$". This works well for the most part, but I just found out that it doesn't catch an address like this ... "john.doe.@yahoo.com" ... where there's a "." right before the "@", which is invalid, so my program tries to send it & throws an exception. How to modify my regex string to catch this situation?

I'm trying to use an Exchange Server to send emails from asp.net web application and atm the mail is getting stuck in the drafts folder and not being sent.Emails are being sent fine if i send them using browser or outlook directly. Also if i go to the drafts folder and manually send the vb.net created emails they re being sent and received fine aswell, but that isn't a long term option.

I am creating a small internal messaging system for my company mainly for phone messages to be passed on. These messages are going to be sent in a form of e-mail which I am perfectly good at coding but the bit I am having a problem is, is contacting the Exchange 2007 Server and pulling up a list of email addresses from the GAL.
I have to make a basic program that: Create a program with a simple interface that
1. Asks the user type his/her email address into a textbox.
2. When the user clicks the "Evaluate Email Address" button, one of two message boxes pops up: "That is a valid email address!" with an "Information" icon, or "That is an invalid email address!" and on a second line, "Please retype your email address.", with an "Exclamation" icon
3. To be considered valid, the email address must -include an "@" symbol, and -it must end in either ".com", ".net", or ".org" or ".edu" (I don't know how to check a string and test if its last four characters end with any of these and make it say not valid email address. I think I might have to use a case statement)
I wouuld like to open outlook with new email with provided subject line, body message and attachment but no email address. User will enter the email address and click send . How can I do this?

I have to set our support email to send an out of office reply between 6pm and 8am every day and then for the entire weekend. I come to find out exchange does not support this. Is it possible to write a "service" that I can load up on a machine that monitor the support email then send an auto reply if it is between 6pm and 8am? Basically it would just be a lite weight email client that only does anything outside of business hours.
I am developing an application which includes the ability to send email. The code works fine for sending internal emails but it fails: server unable to relay mail 5.7.1 when trying to send externally.
This is the code. Public Shared Function SendEmail(ByVal SubjectText As String, ByVal BodyText As String, ByVal Recipient As String) As String Dim msgClient As System.Net.Mail.SmtpClient Dim msgTo As System.Net.Mail.MailAddress Dim msgFrom As System.Net.Mail.MailAddress [Code] .....
I get the same error if I change the password to something incorrect so I'm wondering if the NetworkCredentials are being ignored? I've seen articles where teh IP address of the server must be trusted by the SMTP server or it won't relay the mail but I thought I was doing the same as an email client such as Outlook with the code above: that can be used from any PC on the network without having to specify its IP address on the SMTP server.
What I would like to do is create a command button that launches an email from outlook attaching the current word document to a set email address. I'm not fussed if the word document is saved or not as it is only the email receipent that needs it, likewise I don't mind if the code instructs the email to send of just opens it ready to be sent.I have read through loads of forums and tried loads of codes but cannot get any to work.
im using vb8.net im struggling to make a program that will display email addresses so in other words if im using ms outlook then by the click of the button the program must go in to the windows registry and then look in the place where the email address is and then read that part and display the address in a text box.
i can send email through vb.net behind code but how do i implement so that the recipient cannot see the sender email and only the name?i had done alot of research but i can't find any solution about this problem
I am sending an email using VS2010 VB which works fine, except I would like to have the recipient see their name in lieu of their email address upon receiving the email. I've tried different 'To' addresses, ([URL]), but nothing seems to work. It always shows the email address when received.
I tried to put just the name of the in the .To but that didn't work. Could someone please point me in the direction or show me how to do it?EDIT: My Code is Below...
Dim Subject as String = "Services for " & date.today.string Dim Body as String = strHTML (defined elsewhere on form) Dim oApp as Outlook._Application

I didn't copy or paste as the code is on a second computer and that one isn't network connected. I typed it in, so there may be a typo or two. When this code is executed, nothing is sent.
