[Mailman-Users] Message Delays

[Stevenmark1975 at aol.com]

Hi i run a mailman list and am having complaints from members because , for 
 example an email is sent to the list at 0800 hrs and they are not 
receiving it  until 2300hrs , the members all have different isp mailboxes from a 
variety of  isp's , the message is hitting the server from the sender but is 
very erratic at  getting to peoples inboxes , any ideas as to why , as the 
company i buy the list  through say there are no issues with the list when 
quite clearly there are 
 
Hope you can help
