The mailing list for listmasters using Sympa

[Mark London <address@concealed>]

Hi - I'm trying to configure and customize sympa.   Is there a way to 
error email messages from being sent to the listmaster?   For example, 
if I customize a template, and I have an error in it, it generates an 
email, with the subject line:

Failed to parse web template

That email isn't necessary, because I see the error message on the web 
page itself, when I try to view the web page using that template.

If there's no switch to turn it off, can someone tell me where I can 
modify the code, to disable it?  Thanks. - Mark
