>Release:        NetBSD-current of May, 1
>Environment:

System: NetBSD aie8.aie.nl 0.9a AIE_ALL#0 i386
>Description:
It seems that the routines which write out a mailbox to disk
	are broken, when 1 message out of a list of messages is deleted
	(using /usr/bin/mail), the mailbox that is written back is garbled.
>How-To-Repeat:
With empty /var/mail/sreiz:

$ foreach i ( 1 2 3 4 )
foreach? echo "hallo, body $i" | mail -s "subj $i" sreiz
foreach? end
$ cp /var/mail/sreiz ~/tmp/mbox
$ mail
& d 3
& q
$ diff -w -u ~/tmp/mbox /var/mail/sreiz

It shows that instead of deleting the third message, the mailbox is garbled.
In my case, grep -i subject /var/mail/sreiz gives:
Subject: subj 1
Subject: subj 2
Subject: subj 4
Subject: subj 4
so it seems the fourth message was copied over the third.

>Fix:
unknown. Bug has probably been in NetBSD for a while since a message
	of Apr, 12 (?) in the netbsd mailing list ``hints'' at it.
