SMTP Protocol Event Sink : ISmtpOutCommandSink |
|
|
Hi All,
I'm trying to write a protocol event sink that will change the sender
address when it bounces of a local SMTP server. I got the event to sink to
trigger but get the message "An SMTP protocol error occurred. The SMTP verb
which caused the error is 'MAIL'. The response from the remote server is
'503 5.5.2 Sender already specified".
The code in 'ISmtpOutCommandSink.OnSmtpOutCommand' method looks as follows:
string command = "mail from: bounce-id=12345@mydomain.com\r\n";
context.SetCommand(command, (uint)command.Length);
context.SetCommandStatus(0);
I registered the sink for the OnMessageStart event with FROM rule.
Thank in advance.
