clamd/exim mismatch in jessie
In /var/log/exim4/paniclog for each received message:
2015-02-16 16:43:43 1YNOlq-0007Jp-Ed malware acl condition: clamd: ClamAV returned: /var/spool/exim4/scan/1YNOlq-0007Jp-Ed/1YNOlq-0007Jp-Ed.eml: lstat() failed: Permission denied. ERROR
The clamav user is in the Debian-exim group, and the clamav process is running as the clamav user, so I'm unsure what's going on offhand.

All correct. The issue, it turns out, is this: http://serverfault.com/questions/245229/exim4-wont-send-message
We need to set "AllowSupplementaryGroups yes" in clamd.conf and freshclam.conf
