I have tried phplist for the first time today and I have had almost 40 interruptions of sending sessions !
Don't know if it comes from my provider or from a phplist.
So to check if the sending was blocked I had to go to phpMyAdmin and reload the table phplist_usermessage to see if there was new recorded lines (seeing the entered column was good to show me time of last record).
Is there a hack to check that automaticaly from phplist browser admin interface ?
Thanks
