If these are **personalized** emails, then how they get queued will
depend on how they are built. One person wants a,g,f,t,z and
another wants a,t,q,p,z. If they want them ASAP, then it's not
obvious concurrency is an issue at all; perhaps newsletters with
p go out whenever p changes and triggers them. Maybe changes in
some of the topics do not trigger new email, but wait on a clock,
etc.... In either case, they may still be different per subscriber
because of the other selections (else they are not personalized).
Even with half a million subscribers, depending on the number of
options and the subscriber base you might still be sending only
a very few messages to each site. And if they are truly personalized,
it's not at all clear to me how one would build them so they could
go in the queue more than one by one.
Roughly:
SELECT email_address, topics FROM subscribers WHERE email ='$1' ORDER
BY topics,email_address;
for (@email_address) {
build message(@topics);
qmail-inject message # we do these ourselves one-by-one; personalized
}
Qmail will not be the hard part :-)
If, OTOH, they are a personal selection of independant, non-personalized
messages, batching will make sense - but that's not "personalized".
As usual, a clear statement of the situation will help.
