Hi,
Consider the following entries in an aliases file:
testlist: :include:/etc/postfix/testlist
owner-testlist: user1
content of /etc/postfix/testlist:
user1
user2
user3
When we simulate a locked mailbox by creating /var/spool/mail/user2.lock
and send a mail to the testlist, the following line is added to the mail
log:

6260614005B)

The mail gets forwarded and then sent as owner-testlist.
user1 receives the mail and then the mail goes to the deferred queue
because user2's mailbox is unavailable. Even when the mail server
retries after a few minutes, the mail is only retried to user2 (not
user1). This is the expected behaviour.
Now, when I put the following in the aliases file:
member1: user1
member2: user2
member3: user3
testlist: :include:/etc/postfix/testlist
owner-testlist: user1
and in /etc/postfix/testlist:
member1
member2
member3
I touch /var/spool/mail/user2.lock to simulate a locked mailbox.
When I now send a mail to testlist, the mail is not forwarded and resent
as owner-testlist. The mail is sent to user1 and then deferred. With
every retry of the mail, the mail gets sent again to user1 and then
deferred. This happens until user2.lock is removed and the mail is once
again sent to all addresses on the list.
Is this normal? How can I make sure postfix also uses owner-testlist so
messages are not delivered multiple times when one of the mailboxes is
currently unavailable.
