I'm seeing some strange behaviour with fastforward-0.51 and qmail-1.03
on Solaris-2.5.1. No patches applied to any DJB software.
I have entries in ~alias/projects as follows
teladm-others@:
[EMAIL PROTECTED],
# [EMAIL PROTECTED],
# [EMAIL PROTECTED],
;
teladm-postmaster@:
| forward\ `teladm\ $SENDER`\ &&\ exit\ 99,
;
The teladm program simpy uses echo to generate a new recipient name
depending on where the original mail came from. Mail from me is not
special so the default of teladm-others is generated. Here is the
full text of teladm:
#!/bin/sh
#
# Split mail from the TelAIN sites to appropriate support people
# Author: Gordon Rowell <[EMAIL PROTECTED]>
case $1 in
*esda* | *csda* | *paum* | *paus* )
echo teladm-auc
;;
*hmk* | *lon* | *inp* | *inq* | *int* | *inu* )
echo teladm-one3
;;
*)
echo teladm-others
;;
esac
After making the cdb file I see
cdbdump < projects.cdb | grep teladm | cat -vet
+15,26::teladm-others@->&[EMAIL PROTECTED]^@$
+19,37::teladm-postmaster@->|forward `teladm $SENDER` && exit 99^@$
There are also entries for teladm-auc and teladm-one3 which have the
same value as teladm-postmaster.
The contents of my ~alias/.qmail-default file is
| fastforward -p /var/qmail/alias/users.cdb
| fastforward -p /var/qmail/alias/pizzatrek.cdb
| fastforward -p /var/qmail/alias/projects.cdb
| bouncesaying "Sorry, no mailbox here by that name. (#5.1.1)"
When I send mail to teladm-postmaster I see the following details in
my logs:

Note the deferral line. This message sits in the queue and is
repeatedly resent to teladm-postmaster. Poor Gordon is receiving
multiple copies of the message.
To prove to myself that it is fastforward rather than forward I set up
the following test:
Add the following to projects
dummy@:
| exit\ 99,
;
and regenerate the cdb file.
cdbdump < projects.cdb | grep dummy | cat -vet
+7,9::dummy@->|exit 99^@$

Now create ~alias/.qmail-dummy
echo "| echo 99" > ~alias/.qmail-dummy
cat ~alias/.qmail-dummy
| echo 99
The existence of this file means that fastforward will not be called
for all local mail sent to dummy.

Success. So fastforward is the culprit. If I change the fastforward entry to
dummy@:
| exit\0,
;
And remove ~alias/.qmail-dummy
cdbdump < projects.cdb | grep dummy | cat -vet
+7,8::dummy@->|exit 0^@$
ls -l ~alias/.qmail-dummy
/var/qmail/alias/.qmail-dummy: No such file or directory
then send mail to [EMAIL PROTECTED], the logs show
958104932.675775 new msg 227912
958104932.675970 info msg 227912: bytes 831 from

958104932.780599 end msg 227912
As a workaround, I can change my fastforward entries to exit with 0,
but that doesn't solve the problem.
So, why is this happening?
