I put a script in crontab to send me an email when a backup script has completed.
That script when run by itself does send me that email.
However, when it runs in crontab I get (from syslog)
Aug 15 03:49:02 7 CRON[5237]: (andy) CMD (/home/andy/bin/Send_Email.sh)
Aug 15 03:49:07 7 sSMTP[5241]: Creating SSL connection to host
Aug 15 03:49:07 7 sSMTP[5241]: SSL connection using ECDHE_RSA_AES_256_GCM_SHA384
Aug 15 03:49:07 7 cron[760]: sendmail: 450 Requested mail action not taken: mailbox unavailable
Aug 15 03:49:07 7 sSMTP[5241]: 450 Requested mail action not taken: mailbox unavailable
Aug 15 03:49:07 7 CRON[5236]: (andy) MAIL (mailed 63 bytes of output but got status 0x0001 from MTA#012)
Aug 15 03:49:46 7 gvfsd-metadata[1674]: g_udev_device_has_property: assertion 'G_UDEV_IS_DEVICE (device)' failed
This is part of crontab
# m h dom mon dow command

What is wrong?
