Sorry. My investigation before I posted my message was not very
thorough. I found [1] and [2] where something had already been written
in regards to the new bulk.pl script.

I did some spell checking on both documents.

I do not know “lor” in the following item is. Did I guess the meaning
correctly?

  * Sending TERM signal to Sympa process may need a lor of time to stop
the process if sympa.pl daemon is distributing a message for a huge
list.

  * Sending TERM signal to Sympa process may take a while to stop the
process if sympa.pl daemon is distributing a message for a huge list.

Also a lot of times the word

disponibility

is used. Do you mean disposability instead? I am not sure.

I will.


Bests,
