Why ssmtp events are sent only at restart of zoneminder?

[linforpros]

Hello,
Below is a log before a zoneminder.service restart with events generated and the filter configured to email them:

Code: Select all

and this one is after a zoneminder.service restart:

As one might suspect after a restart of zoneminder I get all unsent events at once.

I have got this line changed in /usr/bin/zmfilter.pl:

### Send the Message
#MIME::Lite->send( "smtp", $Config{ZM_EMAIL_HOST}, Timeout=>60 );
#$mail->send();
$mail->send('sendmail','/usr/sbin/ssmtp',$Config{ZM_EMAIL_ADDRESS});

And a question: why the instructions from the wiki author changed $Config{ZM_EMAIL_HOST} to a different Variable $Config{ZM_EMAIL_ADDRESS} and without a timeout?

Could that be an issue?
