Postfix not enough free space in mail queue

[zorroxz]

Hi,

I need help with Postfix. Postfix shows this errors in the logs:

Mar 5 12:14:11 postfix/smtpd[7569]: warning: not enough free space in mail queue: 2146160640 bytes < 1.5*message size limit

My question is where did Postfix get the size 2146160640 bytes? I could not find anything in the config files that could produce this number.

Postfix config:

cat /etc/postfix/main.cf

disable_vrfy_command = yes
mydestination =
inter_interfaces = all
local_recipient_maps =
relay_domains =
local_transport = error:local mail delivery disabled
mail_name = Service
syslog_facility = mail

smtpd_recipient_limit = 1000
smtpd_peername_lookup = no
smtpd_client_connection_count_limit = 200
smtpd_client_connection_rate_limit = 0
smtpd_client_message_rate_limit = 0
smtpd_client_recipient_rate_limit = 0
smtpd_client_event_limit_exceptions =
scan_destination_concurrency_limit = 200
hash_queue_names = deferred, defer, incoming

queue_run_delay = 60

smtp_connection_cache_on_demand = no

virtual_alias_maps = hash:/etc/postfix/virtual
notify_classes =
bounce_template_file = /etc/postfix/bounce.cf
bounce_queue_lifetime = 5d
delay_warning_time = 6h
bounce_notice_recipient = postmaster
delay_notice_recipient = postmaster

smtpd_client_restrictions = check_client_access hash:/etc/postfix/access,cidr:/etc/postfix/networks.cidr,permit_mynetworks

queue_minfree = 1073741824

message_size_limit = 100000000


Disk size:

ll /var/spool/postfix
lrwxrwxrwx 1 root root 17 Apr 30 2013 /var/spool/postfix -> /opt/data/postfix

df -h (This was not taken when the error occurred)

I can not seem to connect queue_minfree and message_size_limit to 2146160640. Please help. Thanks.
