SMTP Email Client Fails On Local Machine Needs To Run On Client
Jun 29, 2010I have an application that takes a series of reports and sends them as attachments in an email to a specified group of email accounts.
When I run the Java version of this using apache commons and the same setting, the email is sent. However, when I run the VB.NET version of the code, it fails on my local machine and on the client machine.
I have a VB.NET web application running on a server that uses similar code. I tried that code locally and it fails. Yet, the web application is working perfectly.
Why is it that the Java application can send the email, but the .NET application cannot?[code]....
Send An Email Via The SMTP Client?
Jan 3, 2012I'm trying to send an email via the SMTP Client. The following line is rejected

SMTP.Send() Returns After (or During) An Email Sending Session?
May 9, 2011This 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.)

.net - Different Increase In Email Size Using SMTP Class To Send An Email As Opposed To Outlook?
Jan 6, 2010I 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.
Email & SMTP - Program To Send Very Simple Text Email Messages
Feb 17, 2009I'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)

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.
