Hi list,
I am using dovecot deliver for the local mail delivery with qmail. this is working fine.
but when mail is sent to invalid user, it gets bounced back with error "I'm not going to try again; this message has been in the queue too long." rather "no mailbox here by that name"
if there is "no mailbox here by that name", then you should reject at smtp time (in your MTA: postfix, sendmail, whatever).
do not bounce after accepting mail. Search for "backscatter" to learn more.
I could find proper solution, kindly guide to resolve it.
