One 90,000 subscriber messages per day would not be a problem (I am
assuming that you send one email with 90,000 <rcpt-to>s [maybe batched
up in 1000 address chunks, but that is premature optimisation ;-])
The big advantage of exim over the others is that it is better at
determining and using the sites where it can do common MX caching and
delivery (i.e. the likelihood of at least a 1000 of those 90,000 all
going to hotmail/microsoft/whoever is the market leader in the sector
you are targetting, @addresses). So it actually ends up that 90,000
emails is nearer 9000 real SMTP conversations.
