That would appear to be the case yes. With the following config snippet
I added yesterday:
warn condition = ${if
match{$sender_helo_name}{\N^([-A-Za-z0-9]\.)+[a-zA-Z]+$\N}}
!verify = csa
log_message = MIKETEST: Failed CSA - helo($sender_helo_name)
status($csa_status)
Before the other spam filtering, we got 0 results:
[EMAIL PROTECTED] log]# grep "Failed CSA" mainlog.01
[EMAIL PROTECTED] log]# wc -l mainlog.01
496470 mainlog.01
[EMAIL PROTECTED] log]#
