Hi Mark, Thanks. We're getting better performance now once we added this to our sendmail .mc file:
FEATURE(`nocanonify') I wanted to see if we can do further improvements. Right now our email flow is like this for lists: Internet -> ServerA:25 (/etc/aliases mailman) -> ServerA -> SmartHostA Mailman receives the mail and then posts to the same local MTA on the host which sends it out to Smart host. I am not sure we can't just have mailman send directly to the smarthost? What are the implications (on the web site as well as how Mailman functions) if I change DEFAULT_EMAIL_HOST to be SmartHostA? Thanks, Anil PS: Now I am getting about 3000 recips in about 5 minutes. Still not the greatest but it's better than before.
