Perl error with Lite.pm when running filter to send email notification

Hi,

After upgrading to 1.36 (actually, a clean install, restoring DB from backup of an older version) I'm getting this error in the logs when a notification email is supposed to be sent by a filter:

07/06/2021 22:19:29.451385 zmfilter[423574].INF [main:179] [Scanning for events using filter 'EmailOnFrontDoorAlarm']

Any suggestions? I wasn't able to find anything like this from searching around.

I solved this by examining the Lite.pm file and seeing that there are two methods of sending supported, with this MIME module being halfway deprecated. ssmtp is the other method, so I installed that and its dependencies, and everything is working now.

Try msmtp instead of ssmtp. Pleae refer the following links
