I have several mailman list on my Postfix server and all work as far
as I know except for my most important one which is called "everyone"
at example.com. This list goes out to everyone who has an email
account on my Postfix server. I created some test lists today and just
to make sure that mailman was not broken and they all worked. I tried
sending email to some smaller lists and they all seem to work so I
don't know exactly what to do to determine why my everyone list is no
longer going out. I am the administrator for everyone and when anyone
sends stuff to the list, I never get any emails that anything is
pending and when I login via HTML interface, I don't see anything.

Are there any tips you guys can suggest I do for troubleshooting or
perhaps providing some information that could help me understand why
simply one of my lists is not working?

I checked /var/log/mailman/error and really don't know much about
mailman except how to install it and mildly maintain it as far as list
creation and deletion.

When I send to the list and check my logs I see:

That path shown above is a binary file which I don't know much about.

Thanks for any assistance!

mailman-2.1.5.1-34.rhel4.6

**EDIT**

When I login to the list administrative interface & select "list archives", I then click on the most recent date available (April 2008) and there I see all my messages that were never relayed to anyone. They are going straight into the archives for some reason...

Example

I do not run a server...but recently in a install....I renamed my /var/spool/mail and lost mail...I run postfix....but an error log I found under /var/log/mail mentioned mail list....I deleted and re-installed mailman....and got new mail.

2) of course I had set up my /etc/postfix/aliases to the normal login user

3) have you tried sending mail to yourself on a terminal and check the logs?

I would like to add some checks for account "everyone"

assuming you have similar structure....

use root powers and see if you can read or cat /var/spool/mail/everyone....if you can...consider changing your permissions of the other user (say) carlos because it would appear carlos is not a member of the group postfix or mail.

2) an easier way....would use root powers to /var/spool/mail/everyone can give r permission to "others' aka the world

3) if you can use a terminal to send a mail

$ mail -v everyone@localhost.net (or whatever)
subject test cli
done
(press control + d) to send

the cli should give some info or error messages and that leads to

4) pls check /var/lib/mailman/logs/error which may have info to help.

others include command
netstat -atu | grep smtp to check port 25 is up

5) I realise remove and add mailman is not an option for you during normal work time
