HOWTO: Set SMTP status code from the SMTP protcol event sink? - Microsoft Exchange

Hi,

Use pContext.SetSmtpStatusCode() and pContext.SetResponse().

Thanks for reply.

It works correctly in telnet but not in Outlook express.
Context.SmtpStatusCode = Convert.ToUInt32(451)
Context.Response = "451 4.7.1 SMTP session was blocked due to SMTP policy violation by IP " & cip
Context.CommandStatus = Convert.ToUInt32(ProtocolEventConstants.EXPE_DROP_SESSION)
Throw New COMException("Event is consumed", ProtocolEventConstants.EXPE_S_CONSUMED)

The result that appears in OE is:
Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Subject 'dsfsdfsdf', Account: 'SMTP testing', Server: 'mycomputer.companydomain.lt', Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC0F

What is the difference between OE porcessing and processing via telnet?

P.S. I tried to use different error codes like 552 and so on.

Hi,

There is no difference between OE and telnet, it should work with both. I am
not familiar with the .NET-ised framework of the IIS SMTP events, but any
exception leaving the event sink COM server causes the SMTP Service to
crash, so it is a bit weird for me (sure works in .NET). Try it without
dropping the connection (without EXPE_DROP_SESSION), OE may consider this a
more severe event than the SMTP reply and ignore the response code.
