It's hard to say how fast this goes, but it's quite typical:
In: RCPT TO: <[EMAIL PROTECTED]>
Out: 554 <adsl-67-122-166-42.dsl.lsan03.pacbell.net[67.122.166.42]>: Client
host rejected: ACL subscriber
Session aborted, reason: lost connection
If the sender hangs up quickly after see the 5xx, then that's a speed that
pretty hard to beat, plus there are no more bytes wasted.
Since DISCARD means receiving the msg, it could mean receiving some 10's of
KB is the bounce msg contains a lot or all of the bounced msg. That may
not take much time, but DISCARD has the potential of wasting significant KB.
what does the SMTP session look like for DISCARD? Is it a full DATA
command plus 220 + QUIT final handshake so the sender thinks the msg was
accepted?
