Hi, Thanks guys for your comments. I guess I wasn't clear enough in my first email. We are not sending SPAM, but mostly a combination of 1) Invite friends messages. 2) Welcome to the site. 3) Forgot password.
For messages of type (1) we are OK being very conservative. Yesterday Google temporarily blocked my IP when I was sending around 500 of the type 1 messages. I thought that was due to postfix sending messages very quickly and hence I came up with above parameters. I guess i need to rework them. regards, harsh On Thu, Apr 23, 2009 at 8:18 PM, Noel Jones <njo...@megan.vbhcs.org> wrote: > /dev/rob0 wrote: > >> On Wed April 22 2009 17:36:56 Harsh Jain wrote: >> >>> I am choosing the following settings to be on the safe side, so as >>> to not get blocked by any ISP for being aggressive. >>> >> > ... agree with all of rob0's comments. > > # Be Nice >>> default_destination_concurrency_limit = 1 >>> default_destination_rate_delay = 2s >>> default_destination_recipient_limit = 1 >>> >> > The above three settings are fine for a home server delivering to a > relayhost, or a special "slow" transport, but are insane for general > delivery. > > Use the defaults. > > default_recipient_limit = 100 >>> >> This parameter is for queue management.
