Hello Everyone,
I have developed an application in .net frame work, coded in vb.
This application was working for a good 6months until yesterday. a sudden error is occuring which is related to the subroutine(sendEmail)
I have a godaddy hosting&email account which i am using in my application to send async emails to clients.
my trouble is now(all of sudden from the blue) that the server rejects my email and comes back with the following error :
Error Mailbox name not allowed. The server response was: Sorry, that domain isn't in my list of allowed rcpthosts.
A little explanation on the code
so i am using the class
System.Net.Mail.SmtpClient
and simply set up the settings such as port and username/password
and as i mentioned already, the application was working just fine until recently.
i already did a google search and visited multiple forums, they are all talking about Outlook related problems...
could anyone please help?
