I am trying to write a job for sending mail through SMTPClient. I am using gmail server and I am using credentials of my gmail account that gmail gives us for sending email through a program.

I am using these credentials in my dotNet Application and they are working fine. email is being sent.

BUT

Now I am working in X++ and have created a job for sending email and i am using same credentials. But I am getting an error on the line with code:

mailClient.Send(mailMessage);

the error is: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first. v2sm17359467wmd.24 - gsmtp

What is the issue and what is the possible solution ??

my complete code for the job is as following:

static void EmailThroughSMTPExperiment(Args _args)
{
// Set these variables.
str sender = '2011cs163@gmail.com';
str recipient = 'muhammad.g@coh.com';
str cc = 'muhammad.gulfam@coh.com';
str subject = 'Test';
str body = 'Testing';
str fileName = @'C:\test.txt';
str pwd;

List toList;
List ccList;
ListEnumerator le;

Set permissionSet;
System.Exception e;

str mailServer;
int mailServerPort;
System.Net.Mail.SmtpClient mailClient;
System.Net.Mail.MailMessage mailMessage;
System.Net.Mail.MailAddress mailFrom;
System.Net.Mail.MailAddress mailTo;
System.Net.Mail.MailAddressCollection mailToCollection;
System.Net.Mail.MailAddressCollection mailCCCollection;
System.Net.Mail.AttachmentCollection mailAttachementCollection;
System.Net.Mail.Attachment mailAttachment;

SysEmailParameters parameters = SysEmailParameters::find();
;

try
{
toList = strSplit(recipient, ';');
ccList = strSplit(cc, ';');

permissionSet = new Set(Types::Class);
permissionSet.add(new InteropPermission(InteropKind::ClrInterop));
permissionSet.add(new FileIOPermission(filename, 'rw'));
CodeAccessPermission::assertMultiple(permissionSet);

mailServer = SysEmaiLParameters::find(false).SMTPRelayServerName;
mailServerPort = SysEmaiLParameters::find(false).SMTPPortNumber;
mailClient = new System.Net.Mail.SmtpClient(mailServer, mailServerPort);

le = toList.getEnumerator();
le.moveNext();

mailFrom = new System.Net.Mail.MailAddress(sender);
mailTo = new System.Net.Mail.MailAddress(strLTrim(strRTrim(le.current())));
mailMessage = new System.Net.Mail.MailMessage(mailFrom, mailTo);

mailToCollection = mailMessage.get_To();
while (le.moveNext())
{
mailToCollection.Add(strLTrim(strRTrim(le.current())));
}

le = ccList.getEnumerator();
mailCCCollection = mailMessage.get_CC();
while (le.moveNext())
{
mailCCCollection.Add(strLTrim(strRTrim(le.current())));
}

mailMessage.set_Priority(System.Net.Mail.MailPriority::High);
mailMessage.set_Subject(subject);
mailMessage.set_Body(body);

mailAttachementCollection = mailMessage.get_Attachments();
mailAttachment = new System.Net.Mail.Attachment(fileName);
mailAttachementCollection.Add(mailAttachment);
//mailClient.set_EnableSsl=true;
pwd=SysEmaiLParameters::password();
mailClient.set_Credentials(New System.Net.NetworkCredential(parameters.SMTPUserName, pwd));

mailClient.Send(mailMessage);
mailMessage.Dispose();

CodeAccessPermission::revertAssert();

info("Email sent.");
}
catch (Exception::CLRError)
{
e = ClrInterop::getLastException();
while (e)
{
info(e.get_Message());
e = e.get_InnerException();
}
CodeAccessPermission::revertAssert();
}

}

From what I know the connection should use SSL, and I can see from your code that you have commented out that line. Why? Can you try with that one on?

I tried with that line un-commented too but it did not worked. by the way problem has been solved.

Thanx for your reply.

following code worked for me:

System.Net.Mail.SmtpClient mailClient;

System.Net.NetworkCredential credentials;

System.Net.Mail.MailMessage mailMessage;

Email email;

SysEmailParameters parameters = SysEmailParameters::find();

str pwd;

;

email ='muhammad.gh@ciz.com';

if (email != "")

{

mailClient = new System.Net.Mail.SmtpClient();

mailClient.set_DeliveryMethod(System.Net.Mail.SmtpDeliveryMethod::Network);

mailClient.set_Host(parameters.SMTPRelayServerName);

mailClient.set_Port(SysEmaiLParameters::find(false).SMTPPortNumber);

mailClient.set_EnableSsl(true);

pwd=SysEmaiLParameters::password();

credentials = new System.Net.NetworkCredential(parameters.SMTPUserName, pwd);

mailClient.set_UseDefaultCredentials(false);

mailClient.set_Credentials(credentials);

mailClient.set_Timeout(30000000);

mailMessage = new System.Net.Mail.MailMessage("noreply@gggg.com", email);

mailMessage.set_Subject("Test Subject");

mailMessage.set_Body("<b> Test Email</b><br/>something for test");

mailMessage.set_IsBodyHtml(true);

try

{

mailClient.Send(mailMessage);

}

catch (Exception::CLRError)

{

info("@MTu824" + AifUtil::getClrErrorMessage());

}

}

So what solved the problem? Did your e-mail administrator remove the requirement for encryption, or remove the requirement for authentication, or what?

I believe it is a mix of adding this line (I know this property since I also had to use it recently in a local SMTP usage couple of months ago)

mailClient.set_DeliveryMethod(System.Net.Mail.SmtpDeliveryMethod::Network);

combined with

mailClient.set_EnableSsl(true);

but this is just a guess and will let Muhammad explain.
