Connectrix B-Series: MAPS Email Alerts Not Working After Upgrade to v8.2.1a.

• MAPS email alerts are not working after upgrade to v8.2.1a.
• Running a MAPS test email from the switch (mapsconfig -testmail) shows that the email has been sent successfully but there is no email received in the SMTP server from the switch.
• IP Network ping from the switch to the SMTP relay server shows that there are ICMP pings exchanged between devices which means that there is a reliable connection between the switch and the SMTP server.
• Network packet trace (tcpdump) installed on the switch shows that there is no traffic generated from the switch end when there is a test email sent from the switch.
• Crontab command output (Linux command) on the switch (# crontab -l) is empty.

Example:

Bad Switch:

 CID-TAC-6520-AA:root> crontab -l

          # DO NOT EDIT THIS FILE - edit the master and reinstall.

          # (/fabos/sbin/mail_handler installed on Fri May 10 15:49:50 2019)

          # (Cron version -- $Id: crontab.c,v 2.13 1994/01/17 03:20:37 vixie Exp $)

          # Dummy script to avoid firmwaredownload failure

          CID-TAC-6520-AA:root>

• Crontab output shows the crontab list of cronjobs, displays crontab file contents.
• Crontab is a file which contains the schedule of cron entries to be run and at specified times.

Workaround:

1. Log in to the switch as root
2. Run /usr/bin/crontab /fabos/rbin/mail_handler
3. This re-creates the crontab file correctly.

Fix:
This issue addressed in FOS-803652 and fixed in FOS v8.2.1b
