Hi, yesterday, I member tried multiple times to send a to a list, from a roundcube webmailer which is running on the same host as mailman itself. The message is in plain text without any attachments, no HTML either. Yet it was silently discarded by mailman. In /var/log/mailman/vette I find the message Jun 19 21:02:42 2020 (14835) Message discarded, msgid: <************@***>' list: ******, handler: SpamDetect The filter configuration for the list is: filter_mime_types = '' pass_mime_types = """multipart/mixed multipart/alternative text/plain""" filter_filename_extensions = """exe bat cmd com pif scr vbs cpl""" pass_filename_extensions = '' Can anyone say why mailman considered it to be spam? BTW, all messages are scanned by rspamd anyway, which does an outstanding job at spam detection, so mailman's rudimentary spam detection mechanism seems rather superfluous to me. Can't one just turn it off altogether? Cheers, Johannes
