[Mailman-Users] Nomail members

[Denis Morejón López]

Hello guys:
I have about 15 lists. Some of them become a dark hole some times, since 
users can not send to or receive from these lists. I do not see any error 
log in /var/log/mailman/error, only some pck files into 
/var/spool/mailman/shunt/.
I just tried /usr/lib/mailman/bin/unshunt  /var/spool/mailman/shunt but 
although some of the pck files are deleted, It remains the problems with the 
lists.

Some help please!
