Sendmail and slow sending to large list
Hi,
The FAQ mentions that for poor sending performance "You need to turn off synchronous DNS resolution for messages originating from the local host." Well I don't know how to do that with sendmail and I couldn't find out how on the web or in the archives of this list. Can anyone tell me how to do it?
Further detail (for anyone interested): I have mailman 2.0.6 running on a freebsd 4.3 box running sendmail 8.11.3. The smtp log has 104 messages going out every 50 minutes. The machine sits behind a firewall that allows dns from the mailman server to the dns server but is blocking all traffic that is not on port 53 from the dns server to the mailman server. I am a beginner at unix sys admin. I am not spamming anyone, they opted into our mailing list.
Any help would be greatly appreciated.

I recently posted solutions to this, they're in the archives. It might be in mailman-developers, but two or three ways to tweak sendmail have been discussed.
