[Mailman-Users] Tuning Questions for Large List

[Hunter Hillegas]

Not sure the original made it to the list... Resending.

We are running MM 2.1.1 on RH7.2.

We have an announce list with 27,000 members. Delivery to the list takes
FOREVER.

I am looking for some tuning tips.

For one, the default config is using SMTPDirect, not sendmail:

#DELIVERY_MODULE = 'Sendmail'
DELIVERY_MODULE = 'SMTPDirect'
MTA = 'Manual'
SMTP_MAX_RCPTS = 500
SMTP_MAX_SESSIONS_PER_CONNECTION = 0
MAX_DELIVERY_THREADS = 0

Would sendmail be faster?

Should I setup a caching nameserver on the machine to speed lookups?

How do I ensure that messages are being sent efficiently (i.e. AOL.com
recipients are sent in least number of transactions, etc...).

Any help is appreciated!
