Dear list members: could anyone point me to a good site/manual/book about setting up an efficient sendmail system to handle large listserv lists? One of our lists has appr. 1500 subscribers with a daily traffic of 200 messages... I am a customer of LISTSERV CLASSIC for IRIX. Thank you. David PS. Eric you mentioned once that large lists may be configured differently... you must have alot of experience in this area as LSOFT runs some of the largest lists... any tips?
