When i call the Send() of SmtpAccount then i get the following error
"ERROR - Expecting: 250. Recieved: 454 5.7.3 Client does not have permission to Send As this sender.\r\n"
Can u please explain under what condition is this error raised, as the accoutn information specified for creating SmtpAccount works fine for other mail-client.
I found some post about the problem in the google.
Hope it can help.
