ValidateEmailAddress Method


Tests whether specified email address is correct.

This address must be "pure", i.e. without friendly names or comments. To get pure email address of the sender use PureFromAddr property.

The method checks email address syntax and optionally performs simple DNS query to check whether email address domain (the part after "@" symbol) is a valid email domain.

Note: It's strongly recommended that you explicitly specify DNS server name in DNSServer parameter. Although this parameter can be autodetected from Windows, the Windows API functions used for this can produce memory or resource leaks in certain installations.


blnResult = ObjectName.ValidateEmailAddress(EmailAddress, [Options])  
Parameters:  
EmailAddress As String Email address to check. E.g. "user@server.com" or "info@[127.0.0.1]".  
Options As Long (optional) Specifies email address validation level. Higher level requires more time to execute. Options supported:
  • 0 - Perform syntax check only (default value)
  • 1 - Perform syntax check and simple DNS query to validate email address domain
 
DNSServer As String (optional) Specifies DNS server name to be used for resolving host names into IP addresses.  
Return value As Boolean True if email address seems to be correct. False if email address is invalid or can not be validated (DNS server failed, etc.)  
Remarks: There is no 100% guarantee that email address is correct even if its syntax is OK and the domain exists. The only reliable way to validate email address is to send email to this address and then check whether bounce mail returned for this address

Usage example:

Dim Msg, dDateTime
'Using visual basic to create object
Set Msg = CreateObject("MailBee.Message")
'Using ASP to create object
'Set Msg = Server.CreateObject("MailBee.Message")
'In ASP use Response.Write instead of MsgBox
If Msg.ValidateEmailAddress("abc@pbox.server.com", 1) Then
  MsgBox "Email address seems to be valid"
Else
  MsgBox "Email address is invalid or cannot be checked"
End If
