Hi tech@, A new tarball has been uploaded yesterday, it contains the fixes eric@ wrote for the issues reported on asr. For now, only two issues have been reported on smtpd: 1- smtpd does not catch up changes to /etc/resolv.conf; 2- smtpd does not look ip AAAA records; I will not have internet access until Monday but 1- should be fixed by then and I'll fix 2- and republish a tarball to test before I commit to the tree If you ran into another issue, please let me know Gilles -- Gilles Chehade
