Running php list version 2.10.19 on Mozilla Firefox browser my system is not sending messages to about 30% of the members on my active list. My website is www.verslank.net.
It appears as if the problem started when my server limit of 1 000 messages per day was exceeded and is affecting those members on the list that were excluded, however, I am unable to trace the reason why these members are being bypassed and do not know how to rectify the problem.
There does not appear to be a setting in php list in respect of the problem addresses that is different to those of the members whose messages do get sent off.
