Without actually testing and seeing which can be best optimized for your usage pattern? I run postfix without problems, but then, I don't have that much of a restriction on memory so I never really looked into it. I think the memory usage also depends on the kind of filtering you use. Postfix has some additional processes that help in reducing the load by filtering connections prior to actually receiving emails. (postscreen) I don't know enough to say how Exim handles that. -- Joost
