I'm working on an e-commerce website based on ASP Vb. which has auto email(HTML) after people placing order, requesting forgotten password, etc.
MY problem is after email has sent, basically I get bounce back almost from most email careers but gmail. Is there any way to prevent this issue? Here is my email configuration:
webmaster.Configuration.Fields.Item _ ("http://schemas.microsoft.com/cdo/configuration/sendusing")=2 webmaster.Configuration.Fields.Item _ ("http://schemas.microsoft.com/cdo/configuration/smtpserver")= My IP Address webmaster.Configuration.Fields.Item _ ("http://schemas.microsoft.com/cdo/configuration/smtpserverport")=25 webmaster.Configuration.Fields.Update
