** Description changed:
- It seems like after upgrade to 19.04 that exim is not running the
- local_scan function (in my case the sa-exim /usr/lib/exim4/local_scan
- /sa-exim.so)
+ [Impact]
+ Regression causing breakage of spam filtering for Exim4 users when using
sa-exim for spamassassin integration.
+
+
+ [Test Case]
+ TBD
+
+ [Regression Potential]
+ Low. The 'local_scan' function was removed due to concerns it might allow
rewriting of emails in invalid situations. However, this risk has been equally
present in previous exim4 releases thus does not create any new issues, just
restores behavior to what it has been in the past.
+
+ This is the only major change in debian right now (the only other change
+ being a README note).
+
+
+ [Discussion]
+ Upstream dropped support for a 'local_scan' function in 4.92, that sa-exim
requires; Debian restored support for this capability in 4.92-7, but disco is
shipping 4.92-4ubuntu1 without the restored support.
+
+ The reason upstream dropped the support was out of concern that changes
+ in how emails are handled internally will break rewriting in certain
+ circumstances. Unfortunately this breaks compatibility with sa-exim,
+ which uses local_scan to do spamassassin checking to reject spam emails
+ pre-acceptance.
+
+
+ [Original Report]
+ It seems like after upgrade to 19.04 that exim is not running the local_scan
function (in my case the sa-exim /usr/lib/exim4/local_scan/sa-exim.so)
So I now don't have the spam-scan I am used to(I have enabled scanning
by the way of an RCPT_ACL for now)
Hope this can fixed despite sa-exim being very old
