i'm using : - postfix-2.2.3_1,1 - maildrop-1.8.0_3 - courier-imap-4.0.3,1 - courier-authlib-base-0.56 - courier-authlib-mysql-0.56

(all from FreeBSD ports) (without routing to maildrop transport postfix exec normal operations)

i've made a transport and routed mails in it in master.cf : maildrop unix - n n - - pipe flags=DRhu user=vmail argv=/usr/local/bin/maildrop -d ${user}@${nexthop} ${extension} ${recipient} ${user} ${nexthop} ${sender} -w 90

when i send mail i get this in maillog:

Jun 11 01:04:42 ao postfix/pipe[96040]: 50B7A896: to=<us...@domain.tld>, relay=maildrop, delay=0, status=bounced (user unknown. Command output: Invalid user specified. )

but if i execute a "cat mail | maildrop -d $user" in a shell (su vmail) it work

how postfix emulate shell environment to make these differences ? i'm not a coder but it seem other user have the same problem

Thanks for help.
