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 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 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 ?

I think I'm close but how do you get what the text box is bound to? I'm trying to loop through all my textboxes and add a handler that on validation will insert a null if it equals string.empty. How to set the property manager by sending it the appropriate Binding context. I know that this code will not find textboxes in panels or ones that are on other controls, that's fine, for now. I'm also not sure how it will handle controls that are bound to different datasets.

I have posted about receiving email before and this is a follow up of my progress. I have only one form and it consists of 2 buttons, one for downloading messages from the server, the other, to disconnect the connection. I also have one listview and one textbox to display the message. I took the codes from a few open source programming website and compiled them. My program works as such that upon clicking the 'Download Messages' button, a message box will pop up and the user/admin will be asked to enter the POP3 account name. My doubts are I am not sure what POP3 account name to put in.

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.

I'm having trouble coding some new items into a program of mine. The program loops through you Inbox looking for emails that are UNREAD and have a certain subject line. The subject line in this case, is going to search for: "FAX TO: ###########" (actually, it just searches for FAX TO). Next step, I need the selected email to be FORWARDED to the fax number in the subject line - including attachments. In my code - I've already got the message selected - but I can't figure out how to programmatically forward it? I need explicit code help with the following:
1) Check to make sure there are 10 digits in the original subject line. If not - bail out and ignore that message.
2) Trim the subject line and save the phone number to a string
3) Forward the message (plus attachments) to the [URL]
