That's about 10 mails a second (which is presumably not too much of a problem), but it also means you need about 13MB/sec of bandwidth, with is going to require faster than a 100Mbit connection to the internet.

I guess you need to read up on the stuff about tuning transports for problem destinations like Hotmail and setting specific timeouts

Subject: 400 000 Mails in 12 Hours

Hi all !
I have the task of setting up a mailserver capabel of sending 400 000 mail in a max time of 12 hours.
All mails have an attachment of 1 mb. The system should be a mailer for a newsletter system. As I made quite a couple of things with postfix, my concern is the amount and considerations which have to be made when handling such an amount.
