I can't repro that in Xenial. The error message I get comes from the ssmtp sendmail: cannot open mail:25
If you can run strace mpack path/to/file ran...@example.com we could at least see what's wrong. Also, make sure your PATH is correct. Out of the box on Ubuntu, ssmtp installs /usr/sbin/sendmail which might not be in your PATH if you are running as a mortal user. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/240617 Title: mpack depends on execv from ssmtp To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mpack/+bug/240617/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
