Hi,
My OS is CentOS 5.7. 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)

/dev/sdb1 4.9G 140M 4.5G 3% /opt/data/postfix
tmpfs 4.0G 0 4.0G 0% /dev/shm
I can not seem to connect queue_minfree and message_size_limit to 2146160640. Please help. Thanks.

Thanks for your reply.
Unfortunately that is not possible as this is an appliance we bought from some vendor which has customized the OS.

Do they provide updates? You can't be rocking a 5.7 stuck in time....

Talk to the vendor who customized the OS.
