Hello,
I'll have a project to send 300-400k emails a day from a new IP
address with one server. This can build up a signifficant mail queue
on the server.
We have several similar solutions already working but this time the
idea is to have me do this on a VPS (no SSD drives involved),
hmmmm....
Let's take a look at the numbers and bring them down to something we
can
handle in our brains:
400.000,00 day
16.666,67 hour
277,78 minute
4,63 second
Sending 4,63 msg/sec is something regular hardware can do. There's no
technical need to use SSDs or even a tmpfs.
That math fails because usually who send that much emails wants
them to be delivered as fast as possible, so using the whole 24h
account doesnt seem to be the ideal.
The point here is that at the start of this, a temporary deferred mail
queue will build up signifficantly pushing most of the load on the file
system, and the idea is to speed up the queue processing to prevent
killing the server (extending the queue size it can process in a time
frame)
My client wouldn't make a problem to deliver the email after a week but
I'm afraid that queue lifetime is out of the question (again, because of
the queue size it would build up)
