Hello everybody,
from 2 days I had a strange bahaviour in one one Postfix installation
I had thousand of mails in maildrop queue, and I can't figure who
generates it
In the /var/log/mail.log I see a couple of line repeating
Sep 17 14:13:04 helicon postfix/pickup[26802]: F4048C8CD1: uid=4100
from=<$user>
Sep 17 14:13:05 helicon postfix/cleanup[26451]: F4048C8CD1:
message-id=<20130917121304.F4048C8CD1@$hostname>
Sep 17 14:13:05 helicon postfix/qmgr[19330]: F4048C8CD1:

Sep 17 14:13:10 helicon postfix/smtp[26858]: F4048C8CD1:

relay=mail-in.freeserve.com[193.252.22.141]:25, delay=5.2,
delays=0.05/0.03/5.1/0, dsn=4.0.0, status=deferred (host
mail-in.freeserve.com[193.252.22.141] refused to talk to me: 421
mwinf5c34 ME Trop de connexions, veuillez verifier votre configuration.
Too many connections, slow down. OUK004_104 [104])
where $user is the linux user with uid 4100 (it's one of the sysadmins)
The remote server stop to talk to me because I sent too many mail, and
it's ok, what I can't figure out is from where these mail originates. In
the man pages I read that pickup get mail from maildrop queue, but how I
can understand which process put mail in maildrop?
Here my main.cf
mydestination = $hostname, localhost.localdomain, localhost
mynetworks = 127.0.0.0/8, 172.26.2.0/23, [::1]/128
smtpd_use_tls = yes
smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key
smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache
smtpd_tls_security_level = may
smtpd_error_sleep_time = 60
smtpd_soft_error_limit = 60
smtpd_hard_error_limit = 10
smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache
smtp_sasl_auth_enable = no
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
inet_interfaces = all
receive_override_options = no_address_mappings
proxy_read_maps = $local_recipient_maps $mydestination
$virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps
$virtual_mailbox_domains $relay_recipient_maps $relay_domains
$canonical_maps $sender_canonical_maps $recipient_canonical_maps
$relocated_maps $transport_maps $mynetworks
# SMTP policy, if mail queue with bounce grows add
reject_unknown_recipient_domain, reject_unverified_recipient and enable
recipient probe
smtpd_recipient_restrictions = permit_mynetworks,
reject_non_fqdn_recipient, permit_sasl_authenticated,
reject_unlisted_recipient, reject_unknown_recipient_domain,
reject_unauth_destination
Postfix is 2.9.6 on Ubuntu 12.04
Thanks
