i think i haven't been clear enough in explaining the problem...
again,
A (local smtp server) B (remote smtp server)
B is at domain schwab.com, about which i do not know anything, whether it
has qmail, sendmail, exchange or anything else.
1. when A is setup as qmail, and remote address is incorrect@B there is no
bounce from B and the message is accepted at B. I see this at the qmail logs
on A.
2. when A is Microsoft exchange (with MUA as Outlook / outlook express), the
email sent to incorrect@B bounces back immediately.
so my rephrased question is why the behaviour of B is not consistent,
whatever A is.
I just checked this: sent an email from hotmail (which also uses qmail) to
incorrect@B, and the email bounced back from B!
so could it be that i have set up qmail at A incorrectly (case1 above), it
don't think it should matter how the .qmail-default is set up at A.
or maybe i should go back on Monday and check the qmail logs at A again, and
see again if there's bounce message appearing now.....!
thanks,
Ketan
