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"

I could find proper solution,
kindly guide to resolve it.

/var/log/maillog
Oct 24 23:03:27 backup dovecot: auth(default): master in: USER  1       
d at arch.xyz.com       service=deliver
Oct 24 23:03:27 backup dovecot: auth(default): vpopmail(d at arch.xyz.com): 
lookup user=d domain=arch.xyz.com
Oct 24 23:03:27 backup dovecot: auth(default): vpopmail(d at arch.xyz.com): 
unknown user
Oct 24 23:03:27 backup dovecot: auth(default): prefetch(d at arch.xyz.com): 
passdb didn't return userdb entries, trying the next userdb
Oct 24 23:03:27 backup dovecot: auth(default): master out: NOTFOUND     1

no logs in /var/log/dovecot-deliver.log

following is the configuration
.qmail-default
|/var/qmail/bin/preline -f /usr/local/libexec/dovecot/deliver -n -e -d
