I followed this instruction to setup an email client, http://zackreed.me/articles/39-send-system-email-with-gmail-and-ssmtp
All works fine but when I use at / crontab.
for example,
at now
abcd1234
Since there is no such command, an email saying abcd1234 not found is sent to linux-user-name@gmail-username@gmail.com instead of expected gmail-username@gmail.com
Is there any way to override the return address for error/system message on ssmtp instead of setting MAILTO on crontab?
