Before I did ANYTHING else I'd rename all of the 'X-Spam<wotever>'

Many a Sysadmin has chased ghosts that turned out to be the same
header-names already present on the *incoming* traffic - either added by
the submitting server - or even spoofed.
IMHO the best solution is to add the X-Spamwhatever headers in the
system filter based on ACL variables. In system filter it is possible to
remove pre-existing header lines first, but in ACL it is not possible. I
have something such as the following in my system filter:
# Exim filter
if first_delivery then
headers remove X-Spam-Score:X-Spam-Report:X-Spam-Flag
if $acl_m_spam_score is not "" then
headers add "X-Spam-Score: $acl_m_spam_score ($acl_m_spam_bar)"
if $acl_m_spam_score_int is not below 50 then
headers add "X-Spam-Flag: YES"
headers add "X-Spam-Report: $acl_m_spam_report"
endif
endif
endif
For some reason all the spamd ACL examples add the headers in the ACL.
I've always preferred to use acl_m's, add as few headers as possible,
strip as many as practical in router/transport sets.
Tradeoffs, as always....
That said, we're drifting off-topic.
I'm still waiting for better evidence that the original problem is
actually GNUTLS driven.
Haven't needed or used SA for several years now, but ISTR it did now and
then get its knickers caught in the geartrain..
