Couple of our list with over 175 subscribers having problem delivering
messages to all of its members. Some of the messages gets delivered but
not all. WE have not modified the list configuration and were advised to
check for "number of recipient per message" and MAXBSMTP was set to
1000.
 
We never had any problem of this nature before and I am not sure what
has caused this error message (552 5.5.3 Too many recipients).
 
Thank you,
H. Tabari
