Package: cron
Version: 3.0pl1-137
Severity: normal
When esmtp is invoked by cron (via sendmail), it cannot read ~/.esmtprc because
HOME is set to /.
Cron should set HOME correctly for sendmail.
I did
# cat /tmp/esmtp.sh
#!/bin/sh
exec strace -v -o /tmp/esmtp.log -e trace=file /tmp/esmtp "$@"
# chmod +x /tmp/esmtp.sh
# cp /usr/bin/esmtp /tmp
# mount --bind /tmp/esmtp.sh /usr/bin/esmtp
and got
