Hello, it’s been quite a while since I posted here, I kinda miss u guyz:)
I’m running a list of 3 Mil. subscribers for a local news agency as follows:
the whole list is hosted on a 32GBs Ram server, 10 domains, 30 lists, 100,000 subscribers each list..
the mail is distributed thru a relay of 120 servers identified as MX records in the main server’s domains’ DNS zones..
the question is, I noticed that mail delivery is slow, and it gets faster when I use: “postsuper –r ALL” .. do u think it’s a good idea if I added it as a cronjob that runs every minute? or better split the list into several servers??
Thanks..

Hi, Thanks for the tip, but my problem isn’t with deferred mail, no mail is getting rejected from the remote MTA's.. but my problem is that the main hardware node is distributing the mail over the 120 MX nodes slowly.. I have set the SMTP_MAX_RCPTS to 5 per message for better delivery to several MTA's , which means 3 million subscribers are delivered in groups of 5.. resulting 600,000 messages to be distributed by the main hardware node.. is that too much? should I split them to several servers??
Thanks..

Then why would "postsuper -r ALL" have any effect?
Perhaps if you asked your question on a list or forum devoted to configuring hardware and MTAs for delivering large volumes of mail, you'd get a better response. This list is for support of Mailman. As far as I can tell, your issue is downstream of Mailman after Mailman has successfully delivered your mail to your main outgoing MTA and is therefore, not a Mailman issue.

That seems way too low in your configuration. You control the peers of the originating node, so a high SPMT_MAX_RCPTS should not be a problem within your network. What you need to do is make sure that the MX nodes are throttled so that they don't get blackballed by the remotes.
