I've installed IIS 6.0 on my XP professional SP2 and then installed
SMTP Service.
By telnet on port 25 i've reached the SMTP service and obtained the
connection.
Using EHLO command I obtain:

250-dotcom.com Hello
250-SIZE 2097152
250-PIPELINING
250-DSN
250-ENHANCEDSTATUSCODES
250-8bitmime
250-BINARYMIME
250-CHUNKING
250-VRFY
250 OK

I've used RCPT TO: command but after inserted the destination address
server doesn't wait for another RCPT TO:

RCPT TO: guest@dotcom.com
250 2.1.5 guest@dotcom.com

So I suppose that PIPELINING command doesn't work.
How is it possible to use or enable PIPELINING?

Any Idea?
Thanks.

Try reading:

and see if that answers your questions.
