One customer of ours wants to send research reports to all his partners
"instantly" after the data is available.
Our custom application generates the mail files with the attachments. (
personalized per recipient )
These files are then read by an independent daemon and sent to postfix
smtpd with multiple connections
The biggest bottleneck to this system is the disk I/O. ( 15k rpm SAS
drives )
To avoid the double write to disk can I write to postfix queue directly
using some postfix library
I dont want to make smtpd connections in the app because that slows down
the app significantly , and also this is a serialized process.
So sending mails serially slows down the general delivery
Thanks
