If a cron generates any output while it's running, it tries to email it |
| 2 |
to root@localhost. |
| 3 |
|
| 4 |
ssmtp is your default MTA, and it's default configuration points to the |
| 5 |
host mail, at port 25. As mail doesn't resolve to any mail server, |
| 6 |
that's the sSMTP error you're seeing. |

|

If you don't want cron mails, you can redirect ( > ) the output to a |
| 9 |
file or /dev/null. |
| 10 |
|
| 11 |
You could also configure sSMTP to have a reverse alias, so that when it |
| 12 |
tries to e-mail root, it'll e-mail you@×××××××.com. This would involve |
| 13 |
also changing sSMTP to be aware of your ISP's mail hub. |
