We have been running Mailman 2.1.18-1 for a long time, on a Centos 7
system with sendmail. We do a yum update every few months. Coincident
with the last one, which included a kernel update to 3.10, mailman
stopped working, posts are bounced back with this message:
----- The following addresses had permanent fatal errors -----
"|/etc/smrsh/mailman post ampex"
(reason: 1)
(expanded from: <am...@lena.recordist.com>)
----- Transcript of session follows -----
post script, list not found: ampex

Mailman log says the same thing,

dsn=5.3.0, stat=unknown mailer error 1
Qrunner is running, sendmail is working normally. SELinux is disabled.
There is nothing but default in mm_cfg.py, which hasn't changed since 2015.
The yum update can't be rolled back because of the kernel upgrade.
I noticed that the symbolic link in /etc/smrsh was touched about the
same time as the update.
Clues?
