I am using the SMTPClient in my VB.Net application to send emails. It appears it is getting an email signature from somewhere. Where does it get this signature? It looks like it is using an Outlook signature but our company no longer uses Outlook so the signature is wrong. Is there a way to remove the signature before sending the email?
View 1 RepliesI have tried multiple variations of the following code, but I still get the same result. I am trying to have the last line "Issue Description: ...." to appear on a new line. I have tried vbCrLf, vbCr, and & Environment.NewLine & _ None of which work.
Just a note: The other emails are properly formatted. Also, if I add put 2 vbCr (s) at the end of the 'Issue Title' line then it looks normal.This one in particular seems to be a thorn in my side.

This is my first time trying to create a windows application that can be used to send an email message. It's a new requirement that we have to satisfy. Our customer information is saved in a database and we needed to send them some advertisement messages to some or all of them.
I created a windows application but unfortunately I couldn't send a single email message.
I tried to modify my code several times with no luck; each time I'm getting a different exception message. I tried to search the wen for more information regarding this issue but I end up with the same result.
I don't know if I must have an smtp server to relay the messages and be able to send them. If this is the case how I can do that? Is it possible to accomplish this with something else.
Dim Message As MailMessage = New MailMessage()
Dim Smtp As New SmtpClient()

For Host Name I using mail dot metaprosystems dot com, the user name and password are the user name and password I use to log into my mail server. This work when the To address is within my domain. For example bob at-sign metaprosystems.com. It does not work when I send to an email outside my domain. I get this exception in my catch block: "Mailbox name not allowed. The server response was: sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)"
Whether I include an attachment or not doesn't matter.I believe the problem is with my web hosting company, but so far they haven't come up with a solution. I need so advice as to what to tell them to do to fix this. Alternatively,
I'm experiencing a problem while trying to verify an email signature that has sent from outlook 2007 and has been sign & encrypted. I receive this email on the other side (not outlook client) as a mime message (eml file). I have opened the eml file using ADODB stream into CDO.Message object. Now, i'm successfully managed to decrypt the message using CAPICOM object. but when i'm trying to verify the signature i get "incorrect hash" and the process fails.
I have to mention that i'm using as a base code the example from microsoft SDK for CAPICOM. I have discovered that if i sign & encrypt a message using that code example, i can (without any problem) decrypt and verify this email file. but when i'm trying to verify the signature of an email sent from outlook client there is a problem (like i mentioned in the beginning). I have also discovered that the content of the email is encode in UUEncode format. i have managed to decode the UUEncode format using BodyPart.GetDecodedContentStream but whats weird is that something goes wrong during that decode process i know that because on the code example we are trying to find:
BodyPart.GetFieldParameter("urn:schemas:mailheader:content-type", "boundary")
but i get an error message because this parameter cannot be found in the BodyPart. when i'm trying to read the text stream:
GetStream.ReadText
i seeing this weird thing... there are some binary characters that disturbing (apparently) to the function to find this parameter. here is the string:
Thread-Index: Acq1GI5RkfMs/4oXTO6yNp+vV7gabQ==
Content-Class: urn:content-classes:message

I'm planning on using the Smart Device Framework 2.3 to use the signature control panel in a Windows Mobile 5 application using the compact framework 3.5.
The control has the option to save the signature as either a byte array of points, or as a bitmap. Now seeing as I want to store the signature in a sql compact database, I guess the byte array is going to be better. The trouble is, I'm not sure how to render that in a full WinForms application after I've transferred it back to the desktop.
I need to show the signature on a report, so it would need to be an image I could link/embed into the report.
how can i capture a signature from an Electronic Signature Pad and store it in database. is there any particular api or it can be captured just like capturing an image from a WebCam. Is it manufacturer specific?

View 7 RepliesI've got a vb program that sends an email using SmtpClient. I can't seem to get the message to pass the Proxy server (ccproxy). When sending thru outlook, I set the SMTP server to the Proxy server address, and in the username field I add a #and the SMTP server name following the username. I have tried several differt things here, but to no avail. Here is a sample of how I am trying to send this:
emailuserid = "me@mysmtp.com#mail.mysmtp.com"
emailpassword = "mypassword"
smtpserver = "192.168.0.1"
in my desktop application for sending mail I have used,
Dim obj1 As System.Net.Mail.SmtpClient
Dim Mailmsg1 As New System.Net.Mail.MailMessage()
[code]....
It was working fine but suddenly since from yesterday, 2 mails are sent by same obj1.Send() (In both the mails date time are same.) I have not changed code or used any loop for sending mail.
I would like to know if there is a simple way to capture a transcript of the SMTP session when sending email using the System.Net.Mail.MailClient. In cases where an error is generated (ex: relaying denied) I would like to display the whole transcript to the user.

View 5 RepliesI have an issue with the System.Net.Mail.SMTPClient class - when it sends an email via the Send method it does not seem to send the QUIT command after sending the email so the connection stays open indefinitely (or until the SMTPClient instance is disposed of by the garbage collector) as far as I can tell.I thought oh well I must just need to call Close or Dispose on it but neither of those methods exist This is very basic, standard SMTP server usage - every server should send QUIT after it is done sending the other commands used to transfer the email, otherwise the remote server keeps the session open (and some servers have a limit on how many sessions can be open at a time or how many emails can be sent per session) so this could cause some serious problems.
Am I being daft or does there seem to be no way to make it do what pretty much every other SMTP client in the world does? I found a Microsoft Connect topic that had been created about this but it was 4 years old and the response from MS was that they would probably include something in the next version of the framework... which is what we are now on

View 1 RepliesI've this small application I've built which loops thru our database and generates 30000 mails and sends them using System.Net.SmtpClient, but it's not working very well. At times it won't send for a couple of minutes, all in all it takes about 48 hours for all the mails to be sent. Our mail provider says it's because the mail server can only handle 10 connections simultaneuosly and that would be the reason why it halts. I've looked over the SmtpClient class but can't find any property to set max amount of connections. Does this problem sound familiar? Could that be the reason? If so, is it possible to set the max amount of simultaneous connections from the smtpclient to the mailserver?

It would be quite useful, to know if the message was accepted by the mailserver and the message was successfully sent. What I am able so far is, that I can get the SMTP-Server error code (if there was an error (StatusCode 5xx) by using the System.Net.Mail.SMTPClient Object and its SendAsync Function. There, if there was an error, I get an Exception-Object in the Callback-Event of the SMTPClient
I'm well aware that not every mailserver will tell me if the mailaccount truly exists and then reject my mail with an errorcode but instead just accept the message and then delete it. Therefore I would be grateful for another Method to check if the mail was sent (note: not read, that would be the read confirmation)
The final purpose would be: Try to send an email to a recipient using it's domains mailserver and if it fails, proceed according to the errorcode (user does not exist -> abort / mailserver did not respond -> use another mailserver if available).
I have an issue where emails sent out via the SmtpClient class in .NET go directly into the outlook junk mail folder (Outlook 2003 and 2007). If I send the exact same email (same body, same subject, to and from the same accounts as I use in .NET) from Outlook itself, it will come in fine and not be marked as junk mail. The only difference is the extra headers that Outlook appends to the email when it is sent directly from Outlook.

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.
