[Frank Rust <address@concealed>]

Dear all,
After upgrading Sympa to Debian stable 6.2.16 I have errors when the Sympa 
tries to create a notification message:
(This example: add a moderator to a list:)
Can someone help to fix this?
* The folder /tmp exists and has drwxrwxrwt   root root  permissions
* perl is current Debian 5.24.1-3+deb9u5

Thanks in advance, Frank
