Hi all,

I've been running Postfix + Maildrop + Courier IMAP/POP + LDAP on a
RH6.2 for two weeks, with maiboxes at /home/directories in maildir
format. All seems to work fine, except that every day some "lost" mails
appear in the /var/spool/mail. Users affected vary randomly and senders
of these mails are indistinctlly local an not local. Permissions in home
directories are ok.

In the maillog, nothing strange seems to happen, but some delay:

Jan 22 11:12:04 hostname postfix/pipe[1495]: 4E49B3BD10:
to=<userdomain.dom>, relay=maildrop, delay=425, status=sent
(hostname.domain.dom)

I've tried to use "maildrop_destination_recipient_limit = 1" in main.cf,
in order to avoid postfix to attempt to pipeline multiple deliveries to
the same domain into one maildrop invocation. As a result, the behaviour
has improved a lot and I'm getting fewer "lost" messages, but the
problem has not totally disappeared. :-(

Though I'm running filesystem quota in homes partiton, "lost" mails
don't belong to over-quota users.

Here's my postconf -n:

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
debug_peer_level = 2
home_mailbox = Maildir/
inet_interfaces = all
local_recipient_maps = $alias_maps ldap:ldapuser
mail_owner = postfix
mailbox_command = /usr/local/bin/maildrop
mailbox_size_limit = 50000000
mailbox_transport = maildrop
message_size_limit = 50000000
mydestination = $myhostname, localhost.$mydomain, $mydomain
mydomain = domain.dom
myhostname = hostname.domain.com
mynetworks = 172.25.0.0/16, 127.0.0.0/8
myorigin = $mydomain
queue_directory = /var/spool/postfix
queue_minfree = 10000000
relay_domains = $mydestination
smtpd_sender_restrictions = reject_unknown_sender_domain
transport_maps = hash:/etc/postfix/my_transports

I'll appreciate any suggestion-comment-idea...

Thanks in advance!

Albert
