The problem was solved by using msmtp instead:
~# cat /etc/msmtprc
Code:
defaults
tls off
auth off
# ISP
account isp
host smtp.isp.com
from me@isp.com
account default : isp
crontab -l
Code:
25 16 * * MON /root/show.disk.usage.bash
show.disk.usage.bash
Code:
#!/bin/bash
CURRENT=$(df --output=pcent / | sed 1d)
printf 'From: me@isp.com\nTo: me@isp.com\nSubject: Disk space\n\nRoot partition %s full.' "$CURRENT" | msmtp -t
Thanks!
