I think we can fix your issue fairly simply.
Please, as I asked in my reply at
<https://mail.python.org/pipermail/mailman-users/2016-February/080524.html>,
post the output from 'postconf -n' and the contents of mm_cfg.py.
Sorry, I got mixed up. Its just probably the frustration. Everyone
uses mailman, I don't know why I'm so stupid

This is almost certainly your problem. All those checks take time,
especially if DNS is slow. If you send a message from a client and
Postfix takes 5 seconds to accept it, it's no big deal. If Mailman
sends
to 10 or 20 recipients, and it takes Postfix a minute to respond, it
still may be no big deal unless another two posts arrive in that minute
, and so on until you have a big backlog.
I suggest that if you really want all those checks, that you set up a
separate port for Mailman to send to without all those rbl lookups and
recipient domain lookups. See below.
vim /usr/lib/mailman/Mailman/mm_cfg.py
###############################################
# Here's where we get the distributed defaults.
from Defaults import *
##################################################
# Put YOUR site-specific settings below this line.
DEFAULT_URL_PATTERN = 'http://%s/mailman/'
DEFAULT_NNTP_HOST = 'www.mrbrklyn.com'
DEFAULT_EMAIL_HOST = 'nylxs.com'
DEFAULT_URL_HOST = 'www.nylxs.com'
MTA = 'Postfix'
POSTFIX_ALIAS_CMD = '/usr/sbin/postalias'
POSTFIX_MAP_CMD = '/usr/sbin/postmap'
DELIVERY_MODULE = 'SMTPDirect'
SMTPHOST = 'mrbrklyn.com'
SMTPPORT = '25'
Here's where I'm suggesting changes. Pick a port, say 8000, although it
could be anything that doesn't conflict.
Then change the above to
SMTPHOST = '127.0.0.1'
SMTPPORT = 8000
(don't quote the port - it's a number, not a string)
Also, while you're at it I suggest adding
VERP_PASSWORD_REMINDERS = Yes
VERP_PERSONALIZED_DELIVERIES = Yes
VERP_DELIVERY_INTERVAL = 1
for more reliable bounce processing.
But, see below for changes to Postfix master.cf that you must make
first.
add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST)
add_virtualhost('lists.mrbrklyn.com', 'mrbrklyn.com')
IMAGE_LOGOS = '/mailmanicons/'
There is another one in apache:
I don't know if it is being used.
vim /usr/local/apache/conf/mailman/Mailman/mm_cfg.py
No, that shouldn't be used.
In Postfix master.cf add the following stanza
127.0.0.1:8000 inet n - - - - smtpd
-o smtpd_authorized_xforward_hosts=127.0.0.0/8
-o mynetworks=127.0.0.0/8
-o smtpd_recipient_restrictions=permit_mynetworks,reject
-o smtpd_client_restrictions=
-o smtpd_helo_restrictions=
-o smtpd_sender_restrictions=
-o smtpd_data_restrictions=
Make this addition to Postfix master.cf and reload Postfix. Only after
you've done that and Postfix is listening on the loopback interface
port
8000, make the changes to mm_cfg.py and restart Mailman.
