Thanks. We're getting better performance now once we added this to our sendmail .mc file:
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?
PS: Now I am getting about 3000 recips in about 5 minutes. Still not the greatest but it's better than before.
