It *WASN'T* doing "local delivery". *THAT* was the problem. ssmtp |
| 13 |
forwards *EVERYTHING*, including email for "root" (no domain specified) |
| 14 |
to my ISP's MTA (i.e. "smarthost"). When no domain is specified, the |
| 15 |
ISP's MTA defaults to appending the local domain to generate a full |
| 16 |
email address. Root at my ISP was getting my cron job outputs. |

Yes, it did happen to me. That was my most embarressing moment in |
| 19 |
terms of screwing up in linux. What I *SHOULD* have done is set |
| 20 |
|
| 21 |
root=my_user_ID |
| 22 |
|
| 23 |
in /etc/ssmtp/ssmtp.conf and my_user_ID would've gotten the outputs. I |
| 24 |
have that set now, but I prefer to play it safe by stepping on the . |
| 25 |
The root redirection only applies for userid < 10 (e.g. root = 0). I |
| 26 |
don't know if any cron jobs send output to userids between 10 and 999. |
