The following vb6 example codes demonstrate how to send email using Yahoo SMTP server.
Yahoo SMTP Server
Yahoo SMTP server address is
smtp.mail.yahoo.com. It supports both Normal/Implicit
SSL/Explicit SSL (TLS) connection to do user authentication, and you should use
your Yahoo email address as the user name for ESMTP authentication.
If you want to use implicit SSL connection with Yahoo SMTP server, you must set the port to 465.
EASendMail is a SMTP component which supports all operations of SMTP/ESMTP protocols (RFC 821, RFC 822, RFC 2554). Before you can use the following example codes, you should download the EASendMail Installer and install it on your machine at first.
To use EASendMail SMTP ActiveX Object in your project, the first step is “Add reference
of EASendMail to your project”. Please select menu ->
EASendMailObj ActiveX Object, click
OK, the reference will be added
to current project, and you can start to use it to send email in your project.
If you got authentication error, you need to enable Allowing less secure apps in your Yahoo account. Although Yahoo supports OAUTH, but it doesn’t provide mail permission, so OAUTH is not a solution for Yahoo mail.
The following example codes demonstrate sending email using Yahoo SMTP server.
In order to run it correctly, please change
recipient value to yours.
To get full sample projects, please download and install EASendMail on your machine.
Const ConnectNormal = 0 Const ConnectSSLAuto = 1 Const ConnectSTARTTLS = 2 Const ConnectDirectSSL = 3 Const ConnectTryTLS = 4 Private Sub btnSendMail_Click() Dim oSmtp As New EASendMailObjLib.Mail oSmtp.LicenseCode = "TryIt" ' Set your Yahoo email address oSmtp.FromAddr = "firstname.lastname@example.org" ' Add recipient email address oSmtp.AddRecipientEx "email@example.com", 0 ' Set email subject oSmtp.Subject = "test email from Yahoo mail account" ' Set email body oSmtp.BodyText = "this is a test email sent from VB 6.0 project with Yahoo email" ' Yahoo SMTP server address oSmtp.ServerAddr = "smtp.mail.yahoo.com" ' For example: your email is "firstname.lastname@example.org", then the user should be "email@example.com" oSmtp.UserName = "firstname.lastname@example.org" oSmtp.Password = "yourpassword" ' Because Yahoo deploys SMTP server on 465 port with direct SSL connection. ' So we should change the port to 465, you can also use 25 or 587 port oSmtp.ServerPort = 465 ' Detect SSL/TLS automatically oSmtp.ConnectType = ConnectSSLAuto MsgBox "start to send email ..." If oSmtp.SendMail() = 0 Then MsgBox "email was sent successfully!" Else MsgBox "failed to send email with the following error:" & oSmtp.GetLastErrDescription() End If End Sub
TLS is the successor of SSL, more and more SMTP servers require
TLS 1.2 encryption now.
If your operating system is
Windows XP/Vista/Windows 7/Windows 2003/2008/2008 R2/2012/2012 R2, you need to
enable TLS 1.2 protocol in your operating system like this:
Seperate builds of run-time dll for 32 and x64 platform
|Installation Path\Lib\native\x86\EASendMailObj.dll||32 bit|
|Installation Path\Lib\native\x64\EASendMailObj.dll||64 bit|
For VB6, C++, Delphi or other standard exe application, you can distribute EASendMailObj.dll with your application to target machine without COM-registration and installer. To learn more detail, please have a look at Registration-free COM with Manifest File.
For ASP, VBScript, VBA, MS SQL Stored Procedure, you need to install EASendMail on target machine by EASendMail installer, both 32bit/x64 DLL are installed and registered.
