[Mailman-Users] Sendmail

[Webmaster]

hello,
400 mhz pentium 2 320 ram redhat linux 6.0,ive recently installed
mailman,now i had a problem with the memory originally i had 64 ram so i
added another 256 in there it would choke with only 64,so i had to bring the
open connection option  (num_spawns ) down to 1 but it would take forever so
what sould the setting be for my profile running sendmail the default was 5
should i put it at 5? i have pretty large mailing lists 20,000 members
range.
Thanks.
