We got no warning and no email. We do get the daily emails that come in a 11:30PM with the statistics of the messages received, sent, message sizes, etc. however.
Code: Select all
# SSL Certificate Expiration Checks
0 0 1 * * /opt/zimbra/libexec/zmcheckexpiredcerts -days 30 -email
We have not modified the zimbra cron job at all.
If I run the command manually, I do get an email indicating that the certificate is expiring if I set the -days switch to 100 days after installing a new letsencrypt SSL cert.
Does anyone else receive these messages automatically? This caused a huge mess for us because the client had a 3 year commercial cert and it had expired several days ago and we hadn't noticed and we were unable to issue any zmcontrol commands on the server, mobile devices were not able to connect, and a whole range of other issues.
