Microsoft SMTP Retry Interval   
Hello Everyone

We are using Microsoft's SMTP service to send email.  We have
configured the retry intervals through the SMTP Virtual Server's
properties delivery tab.  However, it appears those retry settings are
only used when the SMTP server is unable to even inititiate a
connection to the remote SMTP server.

The problem we are having is that some remote SMTP servers return the
421 SMTP code when we connect, if they are busy.  421 is "<domain>
Service not available, closing transmission channel".  After our
Microsof SMTP server receives that 421 message, it disconnects and
IMMEDIATELY retries.  In our logs, we see us retrying at a rate of
about a dozen times per second!  Then, because of the massive retries,
some ISPs block us as SPAM...

How can I change the SMTP service to either follow the retry setting I
have setup or at least change how quickly it tries to reconnect upon
receiving a 421??

Thanks
Sean

Re: Microsoft SMTP Retry Interval   
Try adding the GlitchRetrySeconds reg value as shown here - the doc is for 
Exchange Server 2003, but this should work with IIS SMTP service as well 
afaik.

Re: Microsoft SMTP Retry Interval   
Great, thanks for your help Bharat.  I've added that and it seems to
be helping.
