The mailing list for listmasters using Sympa

[Dilyan Palauzov <address@concealed>]

        Bonjour,
	I am trying to set up a list to reject mails if specific header is 
included in it, but cannot find information. Could you help me?

	My idea is to evaluate mails for spam before they go in sympa and 
reject them if the spam-probability is too high (that's what my users 
want.) E.g:

        If a mail contains the header:
                X-Spam-Level: ++++++
	(incl. X-Spam-Level: +++++++++++++++++, excl. X-Spam-Level: +++) then 
the mail shall not be distributed, but returned.

        Is this possible?
        Thanks in advance for your answer,
                Dilyan Palauzov
