My client has been operating with the CDO coding to send client e mails for some years, all of a sudden we are getting "The Transport failed to Connect to the server"
The server is BTOpenWorld with BTInternet.com address
BT say they have not changed anything
Tried my server details and coding works but does not deliver, so something has changed
Tried changing port references
The database was created some years ago under Access 2010 or even earlier
