[and exim in different syntax]

Remember that unless the sender side is using qmail or VERP then 2 
million addresses all in this domain would normally optomise down to a 
single SMTP message transaction with 2 million RCPT TO's.   You may 
also find that you get an unexpected speed up at the inject end since 
the domain name may (certainly should) be cached in the MTA and/or 
local dns server/cache and so if the MTA does verification/routing 
during SMTP receipt the first address would prime the config and all 
the others would shoot through very quickly.

I can certainly donate a few thousand addresses from my boxes.
