its my issue
but i to lazy to add cron job for each install
any option to create internal cron system for all the options ?
or to create 1 cron in the system
and the system will run all the others?
You could just use the remote queue processing. I think one API key would work for several systems… try it 
it’s in the manual (phplist.org/manual) on the chapter “sending”
The main problem is that if you have multiple installations, you’ll have multiple directories, and multiple config files.
You might be best off writing a script to add a couple of lines to your cron.tab file.
Lastly, you might want to offset the running of the cron jobs… i.e. if you have 20 processqueue jobs running simultaneously, would they all be independent of each other? Can your database handle this? how about the mail server? Things to think about…
