Hi, I've got some messages sitting in my mail queue that are deferred, with this message: local mailer (/usr/lib/sm.bin/sensible-mda) exited with EX_TEMPFAIL I'm not really sure how to troubleshoot the sensible-mda program, and therefore can't work out where the problem might be. I'm using a built-from-source version 8.12.1-2 of sendmail-tls Any help would be appreciated. Andrew
