duplicate messages when using aliases.cdb

[ganiwu]

Hi all,

I'm really stuck, i've been searching all over the internet about duplicate message problem... I've tried some solutions that i've found, but it didn't work..

I'm using /etc/aliases.cdb , for example i've some aliases for:

all: alias1, user1, user2
alias1: user1

user1 is unix system account, while "all" and "alias1" only served as alias (not system account)

When i try to send email to all@somewhere.org, then user1 will receive two same emails. because qmail seems to process the email twice, as two different processes

I've tried to put:

1. |setlock ./.qmailmsgid.cache sh -c "! formail -D 8192 ./.qmailmsgid.cache || exit 99" in both .qmail-all and .qmail-user1, but still, user1 got duplicate messages

2. also have tried "eliminate-dups" perl script from

http://www.qmail.org/eliminate-dups

in .qmail-all and .qmail-user1, but still, user1 got duplicate messages


Thanks in advance for the help
