.net - Different Increase In Email Size Using SMTP Class To Send An Email As Opposed To Outlook?
Jan 6, 2010
I am sending an email with an attachment using the following Code
Dim msg As New System.Net.Mail.MailMessage(req.EmailFrom, req.EmailTo)
Dim att As New System.Net.Mail.Attachment("C:Documents and SettingsmichaelrDesktop1216259.pdf")
With msg
.Attachments.Add(att)
[code]....
The file size of the attachment is 396KB, upon the recipient receiving the email outlook shows the file size as 543Kb. Strange thing is if I send an email with the same attachment using outlook the file size is 396Kb.I understand that file sizes can increase due to the attachment being base 64 encoded as opposed to just raw binary.What I am failing to see is why outlook send a file which is 396KB in size but in code when sending it, the same file is 543Kb.

I'm trying to get my program to send very simple text email messages. I did do a search beforehand, and found that I was having the same issue as someone else, but the specific question I have was not answered --
I've learned that if you're trying to send mail, you need an SMTP server... I found this list here but every one of them I've tried yields the same "Failure sending mail" error.
Here's my
Dim mail As New MailMessage()
mail.From = New MailAddress("me@mycompany.com")
mail.To.Add("destination-email@whatever.com")
[CODE]...
Is the problem that I need to show "credentials" (i.e. user/pass)? If so, what would those credentials be? Can I use my yahoo email SMTP server with my login info to do it? And is this all I'd need to add to add the credentials?
smtp.Credentials = New NetworkCredential("MyUsername", "MyPassword")
(before the smtp.Send, of course)

I'm using this code to send an email via smtp in VB 2008:

Dim SMTPUserInfo As NetworkCredential = New NetworkCredential("notifications@mydomain.org", "mypassword")
[Code]....
This has had me stumped for the last week, but I think I got a little closer to atleast identifying the problem when I took it home. Ok, the code above doesn't work when I'm at work for some reason. The exception message is: "Unable to connect to the remote server. ". Seems odd because I am simply using the internet to connect to my smtp server to send an email. When I'm at home, this works just fine.
what is stopping it from going through when I'm at work? If I atleast know that, I may be able to tell our network guys what it is so they can allow it to get out.

I'm trying to send an email via the SMTP Client. The following line is rejected
CredentialCache.DefaultNetworkCredentials
The intellisense suggests this one:
Net.CredentialCache.DefaultNetworkCredentials
I'm using the System.Net.Mail Namespace...is this the correct one?

I have a form with a "Send" button to test a code to send SMTP emails.It fires the click event when I hit the "Send" button, but the email is never sent if I leave the form running. When I close it, the email is sent.This is not the needed behavior because the User may never close the Application (this is a Client/Server application, not Web).Below is the code behind the "Send" button's click event[code]...

This vb.net code seems to work ONLY if run... and I keep the program open for an additional 5-10 secs AFTER I see the "email sent" message. If I instead wait 0-1 secs, and then close the prg, the email goes nowhere.Does SMTP.Send() return AFTER the email is completely sent... or just when the email BEGINS to go out? (Sometimes the email body and/or file attachment might be 10k long, and take a while.)
Dim myMailMessage As New Net.Mail.MailMessage()
myMailMessage.From = New Net.Mail.MailAddress(fromEmail)
myMailMessage.To.Add(toEmail)

I'm making an application in which clients can send an SMTP email. In this application a client must select their internet provider, this possibilty already works. While testing it I tried to deactivate the SMTP.Credentials in which a username and password must be entered. Deactivating/romoving this line has no effect on sending the emails.?. I tested it on my office and at home, with 2 different providers. All mails were send.
My question: Is SMTP.Credentials required to send an email or not? What effects can deleting this line have?

I have a script that sends an email via Outlook 2003 (below) The script works fine on 9 out of 10 PC's There is a specific user, however, that it is not working with. When the user executes the code, the message ends up in the "Sent Items" folder in Outlook but the message does not actually send. The only thing I can see that is different from the other users is that there is nothing in the "From" field in the sent message when it should be the email of whoever is sending. All users are on Exchange 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.

i'm tying to send email in my application directly by the smtp server but the server doesn't allow me to do that.The application its used by everyone in the company, so i set the smtp client UseDefaultCredentials to True, but the server replies with this when i try to send an email:[code].....If i set the credentials by hand, the server sends the email. So my problem is how to make this work to everyone? I don't want to have one public/friend var all time in the application with the credentials of the current user?

I am using the EmailMessage to send email message(s) from my local computer. I am also using the SMTP server of my ISP and generally it works just fine. However, some of the emails are never delivered to the destination (bouncing emails) and i get "Mail Delivery failed: returning message to sender" How do i check if the message can be delivered rather than receive the "returning message to sender"? Should i check the destination email server? I have no idea from where to start actually.
